The Bluebird Cafe in Nashville is a little place that only allows singer/songwriters to perform. You MUST do original material there. It's very common to hear the writer of mega hits doing (their own) stuff that you know so well, by major label artists. Cute, quaint little place.

They have a signup sheet each day and only let 25 people do 2 songs each. Mostly guitarists, but there are a few kb players too. Check it out of you get to Nashville !
