Get ready "Back In The Day Café" crowd!

Season 12 of the NBC hit "The Voice" premieres tonight at 8pm on channel 2, and to mark the occasion their YouTube channel always posts a video of the judges performing a tune together.

Enjoy Adam Levine, Blake Shelton, Alicia Keys and Blake's boo, Gwen Stefani, doing a nice acoustic cover of the 90's classic "Waterfalls" from TLC!
