'The Voice' Season 12 coaches, Alicia, Adam, Blake and Gwen, perform TLC's "Waterfalls" acoustic style to get us ready for the premiere tonight at 7:00 on NBC!  I for one will be watching!

Last season Sundance Head nabbed the crown, giving Blake Shelton his fifth win as a coach. Who’ll win this year? 'The Voice' airs on NBC Mondays and Tuesdays at 7 p.m.
