The Sing-Off's Street Corner Symphony Treats OK! To A Cappella Awesomeness

OKMagazine.com was treated to an extra special performance by Nashville natives and a cappella singing group, Street Corner Symphony, when they dropped by our studio in New York City. And we couldn't be greedy and keep it to ourselves!

The group spoke about what it's been like on NBC's The Sing-Off and how the show has evolved their sound in an exclusive interview with OK! while on tour as a featured group in the Sing-Off Live Tour.
