Jessie's vocal skills are impressive. She's beyond just a good pop singer.

She is also an underrated songwriter.

I just love her. I often think it's rather hard these days to find really passionate singers who put everything they have to give and them some in every note and performance. Makes me appreciate the few real ones even more Amazing!!

6:19 is so UNBELIEVABLY RESONANT! She’s been SO good in recent years! Her musicality has gone from over the top to PERFECT.

Her voice sounded so so so healthy here

She's been through so much and is still going through a lot with her condition but somehow she manages to still go out and do this!! Wish nothing but the best for this woman!!

The rawness of this performance and this live/acoustic setting made this so special.

OOH MY GOD I CAN'T BELIEVE YOU REACTED TO THIS PERFORMANCE =O it's been a long time since you reacted to Jessie. Big White Room was made many years ago when she was in hospital due to her heart condition. There was a little boy in her room with cancer. She saw him praying all night long asking God not to die and the day after he was not there anymore.

this performance shows how insane of a vocalist she is, the agility.. everything is so perfect and so difficult

Just one minute in and I'm reminded. She is fierce, singing from deep down.

I didn't think it was possible for her to become better because she was already so amazing, but these last few years has been the proof that you can always perfect your craft! And her tone got even more amazing! Crazy good performance!

Speechless!! She is giving me an even better old Jessie J. I'm blown away with everything in this medley❤️

Jessie was in Great Ormond street hospital aged 11 and there was a young lad opposite her who I believe was suffering from a terminal illness and was having an operation the next day so he prayed.He did not survive the op. she woke up and he was gone, bed empty. . She said to her mum, but he prayed to live. I am sure you can read about it somewhere. She wrote the song 7 years later based on this experience.

This woman here just saved me from depression wayback to 2014 for being an out of school. But Masterpiece, Who You Are, Nobody's Perfect, and a lot of her inspiring songs came into my life. I admire her so much. Her truthfulness, her vocal agility, her range, her emotions when she's singing and everything about her. She's indeed one of the best vocalists in this world. ❤️❤️

She is just stunning. I think seeing her perform in a small setting like that would be a life changing experience. It almost is on video.

Another video that I’ll probably watch again more 50 times

Jessie J is up there with the best

The most born ready singer I've heard, so incredible, and original! One of the best to do it 👑

I just saw your reaction. Big White Room was written by her when she was young. I think her first song. She has a heart condition (Wolff-Parkinson-White syndrome) and she also had a stroke when she was 18. She spent time in the hospital and in her bedroom during recovery. She has gone through a lot. She is definitely one of the greatest vocalist of our life time.

What happened to the “Do It Like A Dude” performance of this show, great video, but that was a highlight performance for me.

Jessie SINGS.

Very underappreciated artist. I remember her in that Chinese singing show, she was breathtaking. She gets better everyday. I love that.

jessie really FEEDS off the audience's energy and she's insanely good at concerts! she's such a impressive artist, so committed singing her heart out and enjoying herself that it makes her shows all the more enjoyable.

You should definitely react to her performance DO IT LIKE A DUDE acoustic in Tokyo... Her beast mode was on and she went off..

Love her so much!

My favorite live performance of her! I listen to this medley every single day! 🙌🏽

This is the best Jessie J reaction I've ever watched. I've seen them all.

The vibrato

She has such a great voice. And she can do things with her voice, with no other of the singer can do: Touching my heart so much.

Thank you Adam for this awesome reaction. I knew you would enjoy this Jessie J performance. Thanks for sharing your knowledge of singing/music with us. 🎤🎤🎙🎙🎶🎶

Big white room is so meaningful.. She was hospitalised when she was 17 or 16 and the boy next to her passed away the next day..

Jessie j always amazes me decade later and she just inspires still 🙌🏾🙌🏾🙌🏾

And come on arrangements! This setting really brings out great stuff in her.

Her chest voice is so much more open more often and it's so pleasant. I love her.

She's a born singer!! She sung a few more songs from this event, her new rendition of "do it like a dude" was to doe for!! Sooo much growth and depth ❤

Such a Beautiful Voice!!!!!

ALways love UR Jessie Reactions👍❤️👏🌷 NO ONE BETTER LIVE THAN Jessie👍😉come on who else but Jess has a ‘thumb War ‘ with a fan while singing ‘Domino’ 😂 What a treat🙏🏻Thanks 4 watching all (except ‘Dude’ songs!!

I really need her to rerecord some of her older songs she matured so much its a whole different vibe. Shes an epic vocalist, she really is! it’s so much fun to learn from her

This woman is always on fire 🔥 I love her so much

25:03 reminds me of morissette's run in her song trophy. anyway, these vocals are so powerful!

Jessie, Ariana and Tori is the vocal trinity of 10's 😎😀

also, Jessie THOSE RUNS!!!!!!!!!!!!

Such an incredible set of performances, truly exceptional! Definitely one of the best vocalists we have today! Do wish we could have seen your reaction to Do It Like A Dude, as you seem to have edited it out, it's one of my favourites 😩. I definitely agree that she's grown into her voice, she's properly gained control of her voice, and refined it to the excellent standard it is now, and I feel she's going to keep improving!

No doubt the best singer I’ve ever heard, most people can’t even sound like this on record with auto tune ect never mind live. The amount of world class live performances Jesse has done in recent years speaks for itself

She's extremely underrated It's sad

Thank you for reacting to this Vevo session ❤️

This is fantastic !!!!!! Thank you so much

She is the example for a great singer. With age her voice gets better and better. I think, her voice grows more and more. With 40 oder 45 her voice will kill most other singers.

I just love your reactions ❤️❤️ god bless

finallyyyyy i was waiting for this from you

OMG - goosebumps over all...

OMG,Thank You So Much To Reacting Again to My Present Generation Idol Jessie J, I hope you will React her 2015 Full Live Performance in Wireless Festival, She's really Amazing Crazy There.

She done a concert here in the philippines singing that song and she invited Morissette to sing with her!!!What an awesome concert,!!!

For whatever reason I didn’t watch her OG video when it came out. Those runs at the end of Nobody’s Perfect had me like 😤😤😤 (stank face) lol. She’s mentioned that she loves Dorinda Clark-Cole as well as Kim Burrell. I can tell that some of the things she does vocally comes from them. Glad to see you reacting to Jessie again. :) Also, in regards to Big White Room, when she was about 11 or so, she was in a hospital bed. Next to her was a young boy whom she heard praying to God not to let him die. The boy passed away the following morning. BWR is a song written from that experience, and she was 17 when she wrote it. Heavy stuff.

CAN. 👏🏽 WE. 👏🏽 TALK. 👏🏽 ABOUT. 👏🏽 HIS CASUAL. 👏🏽 MELISMAS. 👏🏽

At times Jessie can oversing but I love her 😂❤️❤️😊 very talented! 😍

A new song of hers called "I Want Love" is mind-blowing! Please, react to this!
