My sister introduced me to this band the other day. They are freakin amazing. They are an a cappella band from Texas and also the winners of season 3 of The Sing-off. Never heard of that show, but congrats to them. They combine various genres such as as pop, soul, R&B, and electronic music. If you want a full bio on them check out their website.
