*hears guitar solo* "I wanna do that SOO bad..." Me having played guitar for 16 years: Me too man...... me too.

The bass trampling like horses is the most underrated part of this song. Listen to the chorus.

"The grandpapys of metal" No sir, that would be the all mighty Sabbath.

I've loved Metallica since I was a little girl. They have a song for everything and everyone. Metallica offered me comfort, acceptance and understanding at a very young age. They will be my favorite band forever.

Anyone wanna see a “battery” reaction? Well I do

Rest In Peace Cliff Burton 😞

Kill em all is one of the best metal albums ever, period. Lightning in a bottle. Criminally underrated.

You should check out Live Sh*t: Binge & Purge concert video. There's a cool moment at the 3:46 mark where Lars gets up from his drum kit, quickly runs up a set of stairs leading to a catwalk, runs around the catwalk, down another set of stairs where another drum kit and the rest of the band are, and just gets there in the nick of time to start drumming again at the 3:56 mark.

no better way to start the morning than metallica, amiright? happy easter, guys :)

I got to go to the Whiskey-a-Go-Go on Sunset Strip when they were promoting this album. I got a free LP and the whole band signed it. I still have it to this day and will never get rid of it. It is still in the original wrapping and everything. I have been a HUGE fan of theirs since 1983 and do not go a day without listening to them. The passing of Cliff Burton was one of the saddest days in my life. They have not been the same band since. Don't get me wrong they are still one of the best they just aren't the same. Cliff will be missed by us fans forever. 🖤🤘R.I.P. Cliff!!🤘🖤

Kill em all is like a classic dodge charger...will never go out of style

4:23 - 4:50 is the best thing I've heard in my life. Still to this day.

Yep skipping school, the woods, the weed. You're so right. Yes it was an amazing time to grow up.

Well hell, I was about to go to bed, but now I'm hyped up again. Great reaction dude.

I first heard Metallica in 1984 right after Ride the Lightning was released, I saw it at in a record store at a mall and liked the cover and bought it. The first song is Fight Fire With Fire which is Metallica’s fastest ever recorded song and I was blown away at 13 years old. I could not believe a band could play that fast and after listening to the whole album I was sold for life! My favorite band ever since!! Try doing each song from Ride The Lightning, an absolute masterpiece!!!!

True story: Used to jam to Metallica with my walkman in the smoking area where teachers were smoking too. Kids and teachers together chilling between classes.

After 40 years, still the greatest band in the world!

My favorite song on kill em all! ! Back when James voice was on the higher octave register.

Fun fact from my life experience about the four horsemen, when I was deployed in Afghanistan as a tank crew members, every morning I played this song as the fact we need 4 members to operate a tank and also, cavalry is the history of tanks, my mind said; that is the perfect song when I mounted inside my tank!

Funny story, that slower middle riff was actually inspired by sweet home Alabama you’re right. Dave mustaine played sweet home Alabama while all the members were drunk and Lars said “ye man we gotta use that on the album” so they altered it slightly and chucked it into the four horsemen and soloed over it. Rest is history

In XMen apocalypse this song plays when he creates his four horsemen and its AWESOME!!!

That makes 2763 times I have listened to The Four Horsemen.

Metallica 'till my grave... I had huge problems learning this song on bass exactly because of those tempo changes and galloping. My personal favorite from this album is Motobreath... Give it a shot, I'm sure you will enjoy.

It’s amazing to think they were 20 years old when this was released.

Fun trivia fact: "Kill em all" was originally titled "Metal up your ass" -- there is a great live video where they explain the change in title. It's not complicated; it was just verbiage. But that's embossed into my memory.

"you've been dying since the day you were born, You know it's all been planned" That is one of my all time favourite lines of a song

6:12 Don't worry Alex, that's how we all feel every time we hear that part.

Alex: “This sounds like Sweet Home Alabama” Dave Mustaine: (sighs) Yeah....... Thanks Cliff.

This song is written by Dave Mustaine and the middle slow part is actually "Sweet home Alabama". Lars asked Dave if he could actually slow down a bit the tempo of the song, way back then, and Dave as a joke played "Sweet home Alabama". Lars liked ( i am not quite sure if he recognized it ) it and it went that way...

I'm a die hard Pantera fan, but know Metallica has to be a top 5 band all time AND the goat in metal.

That little tritone presolo climb at 08:21 is so evil, and so fitting. Goosebumps!

Man, taking me back. 1988, 17 years old. Smoking out and listening to Metalica was our thing... Always cranked. Our group of friends made our way to Tampa. Monsters of Rock in the "Old Sombrero Stadium" .... Hot hot hot day. Of course smoking and drinking all day... Groups: Kingdom come, Dokin, Scorpions, Metalica and Van Halen.... Metalica comes on and it gets cloudy and starts to rain... Lightning and thunder in the distance. Metalica just jammed the F out. The entire stadium was full and the floor was packed. No one sat then entire time. At that point, that was the best show I had ever seen. Tool at Oz Fest took that many years later. But, man, what a great Fn time that was! I have really enjoyed your reaction videos to Metalica. Thanks for bring me back man.

This is so impressive, especially when you realize that they where around 18-20 years old when they did that:)

Damn, those guys were like 18 when they wrote these album, I'm 35 and all I can play on guitar is "Come as you are"...

In high school, I'd play the first 3 Metallica albums before football games. Shit would get me SO pumped! TEAM METALLICA - circa 1983

I am METALLICA my sister saw them in concert while Clif Burton was the bass player I respect her for that

I get chills every time i listen to this song.

Yes, that part sounds like Sweet Home Alabama because that's exactly what it is, Mustaine play it when they were discussing how to make that slow section and Lars like it without realizing what it was

Alex: "how much more inten-...." Also Alex: *face melting begins*

Def remember... I was 9 when this came out. I discovered them right before "And Justice For All" during the end of the "Master of Puppets" Era.... But everyone that got hooked on them during the mid 80s immediately went out and bought their first two albums.... If you had all their albums, you were the shat. Def remember firing em up and spending hundreds of hours tryin to learn their guitar riffs (remember KZfaq wasn't even thought of). Most had to learn by ear, a friend unless your family had the funds to buy the tablature books. Best era ever. Hands down. 80s!!! Glad i got to experience them.

Am I the only one that cries when they hear cliff playing? Like god damn.

It's so weird that while I'm right in the middle of a Metallica phase, Alex drops a Metallica reaction. Even when everything else in life sucks, sometimes there are little bits of light that shine through exactly when you need them..

I love how you declared team METALLICA while listening to a MUSTAINE song

Sabbath and Priest are the grand dadies of metal, Metallica are the grand daddies of thrash metal.

Oh thank god🙏 finally Metallica! I think you gotta The Frayed Ends of Sanity too

It’s too funny that you caught the “sounds like sweet home Alabama part” Mustaine actually used it as inspiration for that part.

Was one of them guys skipping school smoking weed/ drinking listening to this, MAJOR influence for me to start my own metal band., 52 now and still blasting METALLICA, team METALLICA but MEGADEATH still a great band. PEACE

5:39 "sweet home ala-"

"The Four Horsemen" was written by Dave Mustaine while at Metallica. Then he left the band and created Megadeth, creating the same song, "Mechanix"

So good. I love how the guitar and bass drums are horses galloping.

You 100% described my brother's driving whenever there's metal playing in the car, which is always...lol.

The whole first album is incredible. Only a few bands have had such an epic debut, and they were doing things other bands had never done before. I listen to Megadeth and Metallica, but if I had to choose I would say Metallica. I did not care for the early Megadeth albums -- the first one I really liked was Countdown to Extinction. Whereas I loved every Metallica album up to Load, which I believe is their sixth studio release.

PLEAAASE do Harvester Of Sorrow, it’s soooo badass trust me

Metallica for me hands down. Listened to them since I was a kid. Megadeth was a band i learned about much later

I've listened to this album, Ride the Lightning, and Master of Puppets so many times, I've lost count. Metallica, Megadeth, and Ozzy were my world during my teenage years.

I just about fell off the couch when I heard your "Cut class go to the woods and smoke weed" comment.... Raising hand Slowly. Yes, a VERY amazing time to grow up in :)

Yes it was an amazing time to cut class, smoke weed and listen to this when it was completely fresh. Nailed it

Trust me, I can play this whole song (solos and all) flawlessly! Air guitar, of course..

I grew up in the 80s. This album came out in 1983, when I was 13. So by the time I was 16, this was already a thrash classic, and was played (in cassette form) at least once at every headbanger party.

The Four Horsemen is is one of their greatest.

Back when Lars used a ride cymbal and James had the high voice

5:18 that face! That bass-line there's an attention getter! 🤘

finally reacts to my favorite metallica song... i’m glad you got to experience the thoughts and feelings i had when really listening to this song for the first time 🙏🏽

The coolest thing about this song that no one notices is that the triplets from the guitar and bass drum mimics the sound of horses galloping. Don't believe me, listen again!!

Metallica will always have a special place for me. I was a kid when I first heard No Leaf Clover and that’s when I became a metalhead. For me Metallica is where it all began. Metallica all the way!!!!

Holy shit I've been asking for this for years and I missed it! Cool you did Four Horsemen on the 4th of the 4th month.. Nice touch

It does have a "Sweet Home Alabama" Moment. TURN IT UP.

I remember my true first introduction to metallica was in the very backwoods of Georgia. I was working on an 18wheeler and our driver was visiting his ex and kids. So i was left out in the truck where they were playing Kill em All and Ride back to back on the radio. At first I was disappointed to be out in the middle of nowhere, but then I really just got in to the music. Middle of nowhere, dark, huge truck, loud stereo, it was just perfect. Been a fan every since. The next few days was interesting to say the least. Backwoods sheriffs, jails and all. ahh memories.

We used to play Metallica when I was auto shop class at school, let’s just say that not much work got done that day...🤘🏻🤘🏻🤘🏻

My god listen to cliff wow !!! Best bassist ever!!!

I grew up in the 80’s and I remember all the “stoners” listened to Metallica and Motley Crue and all the metal stuff. Everyone called them losers and drop outs and stuff....I bet all those jocks are now blasting Metallica in their SUV’s taking their kids to baseball practice! Lol I was a skater kid , loved the Sex Pistols, DRI, Misfits, Dead Kennedys, suicidal tendencies, etc..love Metallica now! I wish would’ve listened to metal back then!

Now Mechanix by Megadeth is a must. It’s actually the “same” song, because it was written by Dave Mustaine.

Cut class and go into the woods? Hell brother we were metal heads - we didn't even bother leaving campus before firing up a blunt lmao

100% TEAM METALLICA! Great reaction Alex!

Get it, those classics were absolutely amazing!

Megadeth every day of the week Precision, intricate guitaring, rhythm guitar is like lead guitar not just down picked power chords, i get Daves voice isn't for everyone but its unique and fits the music, can't wait for their new album

The Four Horseman on Easter...Well played sir, well played!!

Metallica was the band that got me into metal (Black Album era), and I went through every album of theirs in the next 2 years. They inspired me to learn guitar, and over 20 years later, still my favorite band. In that time frame, I have become a Megadeth fan, and huge fan of Mustine and his song writing/lyrics. Metallica will always be my favorite because of what they mean to me, Megadeth has become what metal is to me.

"What more would you want out of life?" Well, they're still putting out albums so in a way, I could replicate that😂😂😂

in 1989 when I was 13 i would listen to this album on cassette tape every day as I walked to school and back home after.

This is the Metallica I fell in love with. Raw, in your face, underground power! This was back when metalheads stuck together and mainstream was blah lol. RIP Cliff!

It sounds like a horses gallop! That strumming technique is actually called a "gallop" for that very reason.

I always loved this song!

I love playing this on guitar, it makes me feel like I'm better than I am for a few minutes.

I'm sure you've seen many requests for Damage Inc, Whiplash and Dyers Eve (that one kicks you in the teeth from the get go!!!)

This reaction absolutely made my day!! Truly underrated tune. You must be exhausted!!😂

I was in the eighth grade when this album was released and this song is my favorite off of this album.

"I JUST WANNA PLAY MUSIC!!" Same bro, then i picked up drumsticks like 4 years ago and now im a taller Lars 🤘🤘

Team metallica all the way. Best instrumental band ever

fun fact: During Archangel's transformation in X-Men: Apocalypse, this song was playing to symbolize the gathering of the four horseman as predicted earlier in the movie.

You're by far the best reactor out there, you're just always yourself, i love it!!

I like how the guitars sound like horses galloping.

4:26 I love that change in tempo.

My right hand gets sore even hearing this! 🤣🤣 it's such a workout! Love it!

That section was actually inspired by "Sweet home Alabama" Dave said cliff was a huge fan, and he played the hell out of that song. That's funny you foud the connection. Lol awesome you picked that out!

Fun fact...Cliff Burton patterned that last transition after.... Sweet Home Alabama lol. He was a fan of Lynard Skynard and it was kind of a inside joke to the band to add that part. Just a cool internal tribute to them in the song

I keep forgetting how crazy Kirk went on that last solo. Almost went Van Halen. And of course Cliff just kept that solid bass going. What a badass lineup this was. And yes I know Dave’s contributions and how they lasted for a few albums even though he got kicked out right before they recorded Kill Em All. What a legacy all of these dudes are leaving behind when all is said and done, and yes that’s including Dave.

Team METALLICA all the way, its all about melody and personnal choice, but Megadeath is so impressive :)

gotta love how he picked up on sweet home alabama, i think dave explained how that influenced the break section in a video before.

Love this song! "Hit the Lights" is an incredible track! This whole album is fire.
