The Voice comes back to NBC on September 23rd with all the good stuff we love! Kelly Clarkson, John Legend, Gwen Stefani and Blake Shelton! This is probably one of the best coach line-ups in a very long time! They all came together to sing a song for us. They did a cover of Extreme's 'More Than Words' and it is EVERYTHING! Plus, check out Carson Daly on guitar! What?!?!?!
