Before heading to Hoosier's Lounge inside Casino Aztar for scheduled performances on Friday, February 8th, and Saturday, February 9th, Nashville, Tennessee a capella group, Street Corner Symphony to talk about how they got started and treated us to an impromptu performance.

Comprised of brothers Jeremy, Jonathan, and Richie Lister, and college buddy's, Adam Chance, John Martin, and Mark McLemore, Street Corner came together in May of 2010 and competed on NBC's a capella singing competition, The Sing Off. Since then they've released albums and worked with artists such as Sing Off judge, Ben Folds, Allison Krauss, and Take 6's Claude McKnight.

Watching them perform live was pretty amazing. All six members each have their own part. One or two sing, one provides the drum beat, another lays down a bass line, while the remaining members take care of other harmony's. It's really impressive! Check out their performance of Radiohead's 1993 hit "Creep" along with some additional info about how they came together in the interview below.
