The Exchange throwing it DOWN performing "Sing" by Ed Sheean at The Sing-Off show Huntsville, AL 

**DISCLAMER: I know & apologize about the base distortion, the base was cranked up at the show**
The incredible vocal group The Exchange (in this person's opinion, should have won the Sing-Off this year) performing at The Sing-Off tour. My first time seeing/hearing them and I was immediately hooked! Insane talent!
