Yes it's all Geoff (pronounced as Jeff Castaloochi) and he can sing the high parts too.It;s his silky smooth tone that impresses most people. And the fact that you can hear every word. Geoff learned to extend his bass by using the growl technique originially but now can go very in low in chest voice. And even lower using subharmonics. He does videos on how to sing low, or very low. Maybe take a look at those..:)

This man has a phenomenal voice. When I first heard him sing as a baritone I didn't realise it was the same man. His tone though still warm, was lighter and for me... (from England) he seemed to have a lighter accent than the rest of his group.. (Voiceplay a capella). I've bdeen hooked on him and Voiceplay since.. There are a lot of videos, mostly theatrical as they all love to put heart, soul and everything else they have into each production.. Subscribing in the hope you are too curious not to check them all out. 🤔☺️

Geoff not only hits insanely low notes but his timbre is just gorgeous. Definitely check out 16 Tons-and he’s going to drop a new cover of Bill Withers’ Ain’t No Sunshine tomorrow. There are quite a few excellent low basses on KZfaq at the moment. Tomi P just released a cover of Avi Kaplan songs with Efe Sayin-it’s pure bassy goodness. And of course there’s Avi himself-used to sing with Pentatonix, now has a solo career. Peter Barber is an operatic bass but has some really sweet bass covers of a bunch of songs. He, Tomi P, Bobby Bass and Marwan Ayman are part of a group called The Bass Gang. And then there’s the Wellermen’s version of Misty Mountains-they recruited a whole BUNCH of basses to rattle the rafters in that one. Colm McGuiness…. You won’t have any problem finding music to check out.

The voice of unearthly beauty!Thank you, my friend Frank.Great reaction!This was my recommendation, I also advise you to listen to his song "Sixteen Tons". Not so long ago, an a cappella VoisPlay song "The Dragonborn Comes Skyrim" was released, in which Geoff also sings.👏👏👏🇷🇺

I second the suggestion that you might want to watch his tutorials on singing low. A couple of years ago, in his role as the bass in the vocal group Voiceplay, it was kind of a major thing for him to reach an E1, and then it took him a while to be able to do it consistently enough for him to sing it live, and now you will hear him reach B0. He is very serious about constant practice in order to expand that lower range while still retaining his high notes.

I love how you're trying to see if you can go as deep as Geoff and each time he goes lower you clasp your head in amazement! Try listening to his Monster Mash it's hilariously great!

Geoff has a 5 octive range and he blows me away every time I hear him! I love him, and the group he sings in Voiceplay.

My favorite thing in the world is watching someone react to Geoff Castellucci for the first time. The reactor (you this time) hears his first low note, says Wow, that's really low, or some variation. I laugh every time, because I know what's coming! Great reaction, thanx so much for giving him a listen. He has a new piece coming today, I'd love for you to check it out. He is the bass singer for an acapella group, Voiceplay. They are unbelievably talented, I recommend that you hear them as well. Maybe start with Hoist the Colours, from the Pirates of the Caribbean 3.

Check out brothers in arms by home free the bass is amazing in that one

He's releasing a new cover in 3 hours at 12 noon EST. I've heard it and it's awesome!!!

You didn't look ridiculous you just look like everybody else who has fallen down the Geoff Castellucci rabbit hole. Check out his cover of The Beatles "Blackbird" among others. Also check out the channel for Voiceplay, the acapella group, of which Geoff is a founding member. Enjoy the journey...

Geoff has a 5 octave range.Amazing.

This rendition of Tolkien's poem was utterly perfect. Captured the mood of the dwarves and the spirit of Tolkien's Middle-Earth. Transports you to another time and place.

Geoff is a rare talent. His range is just sick. His G1 low notes are the bomb and he uses different techniques - chest, harmonic, growl etc. There are lots of great bass singers but Geoff is the king in my book.

Blackbird is my favourite. The last note is beauty 😁👌

As a veteran, 6:13 to 6:20 spoke to me most in this song. It is the warrior's parting words to "hearth and hall," the familiar places which we inhabit on a daily basis. This is the warrior's march to unknown, deadly places. The harmony here nearly caused me to break down.

Welcome to the rabbit hole of Geoff Castellucci. You can’t go wrong with anything that he has done. His range is phenomenal. From B0 to A5. Thank you for reacting to him and I hope to see you reacting to more of him. Great reaction! I highly recommend you react to his new song Ain’t No Sunshine When She’s Gone. You will not be disappointed. It will blow your mind!

Love Geoff! It's an adventure reacting to anything he does on his own or with VoicePlay. His "Ain't No Sunshine" is fantastic!!

He considers himself a baritone. He has a 5 octave range and recently hit a b0. He is in a group Voiceplay and also has a solo channel with videos about how to sing low. As well as solo performances. He usually uses subharmonics to go low

What always amazes me is the butter smooth tone of his voice.

Great reaction... Geoff surprises me constantly...

The Geoff Quartet. His bass is so buttery smooth. He is my favorite bass then Tim Foust of Home Free and of course Avi Kaplan.

Oh this guy, I've seen him before, he did a great cover of Tennessee Ernie Ford's Sixteen Tons

I am a natural bass and this was still my first reaction to Geoff, lol.

Holy shit you had so much power when you tried singing low

Geoff does solo work but to really see him check out the group Voice Play. You will have a great time going down that amazing road.

Geoff's low notes in this one were in his chest voice because he is a freak of nature, but he often utilizes a technique called subharmonics to get really low. I would recommend checking out that technique if you want to extend your low range a bit more. I can normally sing comfortably down to a D2 in my chest voice, but I can comfortable sing a g1 like he did in this song utilizing subharmonics. He has a tutorial on his page and there are many more on youtube

What madness is this, you wore your life jacket what about us, that was so deep I nearly drowned.

If you want to see a perfect example of his 5 octave range, Check out his rendition of Blackbird.

Man, that was a very good reaction!!! Loved!!! I really recommend the cover of the emperor's new clothes from bass gang!!! You're gonna love it!!!

Now check out Geoff's Big Bad John, and his newest one, Ain't No Sunshine. Two more videos where you'll see 4 of him. Like also in Monster Mash.

👏👏👏👏👏👏👏

Thank you, I thoroughly enjoyed your reaction. I can't help but giggle seeing the reactions and expressions of people hearing Geoffs low, low notes but equally enjoy the appreciation of his higher range.

Geoff has quite a few great songs, often acapella. I like "Sixteen Tons" and "The Bare Necessities". He also has videos on how to sing "subsonics" which is what he is singing at the very bottom there. That might be fun to watch you review?

Geoff did a tutorial on how to better hit low notes, very interesting to watch

Great Reaction! Definitely check out his other stuff on his channel. Also, he's in an acapella group called Voiceplay. They're amazing. (Geoff has a 5 octave range and if you want to hear it all, check out Blackbird)

Geoff has a 5+ octave range....in their cover of the Halo theme..he hits a B 0.....his range can be seen at its best in the song From the movie The Nightmare Before Christmas, The Oogie Boogie Song....you see his WHOLE range.......enjoy.....>^^

Geoff has shown he can go stupid low he’s gone to a B0 in chest and sub harmonics but he can always go even lower without going into sub harmonics. BTW he’s part of the A cappella group VoicePlay

Up until I saw Geoff Ihad played with vocal fry, but only really sang in chest. B1 was my normal lowest, but sometimes if I sang firstin the morning I mightget to a G#. He has a video on his channel talking about how hehits low notes. Between him, David Larson, TomiP and afew others, after listening to how they do it. You can activate your false folds to vibrate at half of your normal vocal cords, andvocal fry is definitely the way I activate mine. I can now hit and E1-F1 now, I'm working towards a C1 or B0... I think I have room for the B0, just training oneself. You should def check out Geoff's channel.

2:29 is Subharmonics, you should look it up, it's very interesting :)

there is a video of this same song done (In Dwarvish) it's only 2:25 in the book the Hobbit the song is song by the dwarves, so Colm McGuinness seams to have good rang in the song. The Hobbit - Misty Mountains (In Dwarvish)

If you want to see Geoff hit the lowest note you've ever heard before, check out his cover of Blackbird.

Geoff has a voice like hot buttery caramel wow I love it

You need to react to Geoff's The House of the Rising Sun, or the Beatles Blackbird. Also try his Take Me Home Country Road.

Try Peter Hollands version of misty mountains featuring Tim Foust of Home Free. And watch the picture on the very last note of the song. Also check out Tim Foust music he has several solo song and an acappella album. Called pieces of me that have a few singles releasted from. And they are great. Austin Brown has his own YOU TUBE channels and a music channel. Adam Chance also has a music channel.

Please adjust your camera placement so that your face won't be covered up unnecessarily by the video you're reacting to. Experiment with were to set up your camera so you have more free space in which to place the video. In fact, you can actually edit your video so that it is smaller and sits in one corner or edge of the larger video you are reacting to. Visuals are also important, not just the audio.

Three words... Oogie Boogie Song VoicePlay cover with Geoff taking lead. The man is proof there is life on other planets and come to earth to make us feel inferior. Seriously the man has a 5 octave range!! Need to check out Oogie Boogie of course but also his covers of 16 Tons, The Headless Horseman, Big Bad John, and Blackbird. He clones himself so he can accompany himself. The first video I saw, before VoicePlay even, was Geoff's 16 Tons, I thought it was a group of identical quadruplets.

Please check out ANGELICA HALE recently recording performance EASY ON ME outstanding performance.

Geoff.. or Jeff please rect to Voiceplay

Nice try dude, you just don't have the resonance.

I like Geoff, I do! But the Peter Hollins/Tim Foust version was MUCH BETTER than this one.
