Heart Attack - Demi Lovato Cover (A Cappella) - Backtrack (feat. Spencer Beatbox)

[@spencerx]

I speak guitar.

[@WhatTheElisa]

It's sad everytime they say acapella people asociate it to either pentatonix or pitch perfect, you're the probe there are more awesome acapella covers out there. This is great!!!

[@nicoletrujillo2585]

I like you comment

[@spencerx]

Thanks!

[@cloudiamisal4246]

Hi spencer...i am your fan

[@SimonaAndreaBella]

I almost cried with emotion!!! You are F-A-N-T-A-S-T-I-C!!!!

[@Claire-qe7xh]

i heard the first 3 second... i give a thumps up

[@bmwsFTK]

I know you all usually do the newer songs, but the 80's have some songs that you could blow up. Beatbox, in the decade it really kicked off. You guys really do a superb job, with the songs you cover.

[@andrewbass9364]

Kevin and Avi make them so great. Also their style of arrangements is incredible. But Backtrack has got a great thing going.

[@notnono5342]

I'm usually real picky about covers but oh my this is beautiful

[@jkshepherd]

Omg this is so PERFECT

[@withlovexjay]

Let me try again. I think your voices blend really well together. The arrangement was good and you guys seem to make something that is really hard to do, seem easy and fun. Good job and don't quit.

[@gloomydread23]

the beat so amazing and they sound so awesooome!!!!

[@ryanackerman5705]

That soprano is an absolute BEAST. wow!

[@mynameiskrysta]

One suggestion... Or two... Make the bass louder and the bass should always be slightly muffled (it simulates lower bass)

[@MrSengajafy]

watching this over and over again and still getting goosebumps :) you're awesome, keep it up

[@DominicMGeehan]

Kara's part gave me chills. Definitely listen to this with a good pair of headphones. Great work guys!
