First Performance from NBC's The Sing-Off! 

It's so refreshing to see pure, unadulterated talent.

SoCals NOTA and NOTEWORTHY ARE AMAZING AND CLEARLY SOME OF THE BEST!

man, they've really improved quality of singing groups in recent years

Well... I thought that all of the groups were fantastic! The season was too short (C'mon NBC... less than a week??? Are you kidding???? This is GOLD!!!!!). This show was probably the highlight of my holiday season!

I'm geeking out big time!!!

thank you NBC! bring us more!

Love the Beelzebubs! I have a couple of their albums and they came and performed at my high school back in 2006

All these groups are winners! What a great idea for a show - I'll be watcing

This was a GREAT performance. It made me clap at the end.

When the guy from Nota jumped in it started SOARING

Omg thank you soooo much for putting this up. Been looking for info for this show for the past week, can't wait for the premiere! So glad a capella is getting some recognition now, Glee has opened doors!

LOVE Noteworthy!!! And the girl with the mohawk is amazing!!!

GAHHHHHHHHH! I LOVE THE GUY WHO HAS THE GLASSES ON AND WEARS THE PURPLE SHIRT! HE IS SO CUTE AND HAS A PERFECT SINGING TONE FOR THIS SONG!!.

Can't wait for this year's edition!

this gave me goosebumps!..5 stars!

AMAZING! i'm hooked

They should have had the whole cast sing Bohemian Rhapsody! That would have been amazing!!!

A stupendous and radical performance. I loved it.

I really want this show backk. i loved it.

The girl from Noteworthy has a HELL of a voice. Wow! I've watched this literally over 30 times today xP

The steps were coordinated so well...

GO NOTA!!!! I was there this night and it's going to be an awesome show!!! thanks for this link

Awesome cooperation between the 8 groups!

wow amazing! about time something worth watching!

Wow wonderful!

This gave me chills

I, um... I think my head just exploded. I've been waiting for this for so, so long.

love it

Good stuff. Looking forward to this.

This was a great show.

amazing!

NOTA are the best and it they let it see since this first performance God bless Puerto Rico !

They Bodied It!!!

so good

amazing

Tufts Beelzebubs just finished their sold out concert here in Singapore. They were amazing!!

Voices of Lee is also not a prearranged group. They are a group from Lee University which is located north of Chattanooga, TN. Lee University is why they are called voices of lee.

wow I am surprised how much better the groups are this year.

It seems good. I hope to see more of it.

How can I not have heard about this!!!???

hell yes a cappella!

Ok now that was funny! I actually laughed out loud.

this shows so sick

acapella love :)))

Noteworthy you are amazing! Can't wait to see the show. And Amy I freakin love your hair. Sounds to me like someone is a little bitter!

Woooooooowwww

yeah nicole has some amazing ... talents... all 2 of them...

NOTA NOTA!! FROM PUERTO RICOOOOOOO!!

Fierce!

Go Nota!!! Boricua para siempre

I am so not a Gleek but I like this show. Yay, new episodes next week.

I'm speechless...

DUDE! That was so awesome! Almost better than the original! :D

I love you, face!!!!

Massa, muito massa!!!

hahahah love this show soooo much! season 2 is even beter! but they need to make it longer and open it up more. like open auditions and accept like 20-30 groups. then slow elimination! that would be amazing!!!! love it! and not just cuz i love glee.... lol

that was tight.

They group is called the Beelzebu's or "Bubs" for short. They're an a cappella group from Tufts University

i like nota the best

Somebody should slap this smile of my face, although I doubt it would help, because this video is just to good...

this is the best vidio ever

is this really live?? how does the system even support so many microphones?! its absolutely breath taking if its live.

I think the geeky blonde guy with the glasses has the best voice!

This is better than american idol. I'd prefer show like this over "american next top model" anyday. The U.S NEED more show like this. It's full of talent and creativity.

NOTA - winners of Season 1 are the best!!!!! Just saw their new video for "All I Want For Christmas Is You" on their channel - NOTAVOCAL ... its AMAZZINNNGGGG

Face rocks my face. Go Boulder!

The beginning reminded me of "Ice-ice Baby" it just did :p

the efforts there

I wish someone would post all the performances.

Woah. I likey

GO SOLO!!!

so cool...=)

waaa yo tbn me meti por el werever hahahah pero numanchess estaa megaaaaaaaaaa de lujoo , Un remixer Humanoo!! estaa uuff

OMG Glee what have you done!

@ham5063 could not agree more with you. this girl blows everyone away.

VOICES OF LEE

Oh amy. You scream like a goddess then and now. Although, i must say you've come a long way between seasons 1 and 3!

that is so cool, it would be so hard to do

Wow I was just watching Tencious D do a cover of this song.

OMG! (I don't even say OMG) But I can't wait!!

wow this years groups are MUCH better

Oh one of the few competition shows I like! It was amazing show and I'm rooting for Nota, Bub's, Socal, and Note. Though I disagree with picking Max Factor over Solo. Great upload and nice definition in the picture.

I love the part @ 1:07!

How is it I missed this show when it aired?? I agree with other posters who said it needs to be renewed and placed on the programming schedule AGAIN!!

voices of lee are the best!

Pure amazing... what was that? Like 60 mics or something? :) Great... the best singing show ever...

@kevanmate Sound engineer's name is Ed Boyer. He does a lot of work on a cappella albums as well. Good guy.

NOTA FOREVER!!

wow

Note to NBC: Here in Puerto Rico we also have cities and towns (78 to be exact), so it would've been nice if the graphic for Nota actually said where they were from, instead of just "Puerto Rico". Just a thought.

nick l is sooo gorgeous

Vote for FACE the whole way! Great guys and powerful music.

@singlouder08 YESS ! :DD I love that I'm not the only one who is obsessed with the office to know this wonderful fact.

BEELZEBUBSSSSS

BUBS BUBS BUBS

@hobo59, it's called "casting for a reality tv show" so vocal ability alone wasn't the only thing considered during the audition process. The ability to be visually entertaining (it's a tv show after all) is important as well.

aki anda puro cachorro!!! W2M !!

does anyone know where to find the Sing Off opening theme? that 30 second ditty is caught in my head :P

the second season was so so much better XD

Oh and NBC wasn't even ashamed of ripping it off. Their promos were "Glee meets American Idol". Both shows from FOX. LOL I loved that performance and then it went downhill. I liked the group from SoCal, the girls in yellow and the old ladies. And the second group kicked off sang better after they got kicked off than when they were competing !!!!
