"The Sing-Off" still seems fresh and this season has a new judge to replace Nicole Scherzinger, who left for "The X Factor." Sara Bareilles is the new judge and she had a lot to say about Afto-Blue. Afro-Blue is a Jazz/Pop fun loving a cappella group who formed at Howard University. The group chose to sing the their version of the already Jazzy 'Put Your Records On.' tune by Corinne Bailey Rae.
