I just got home from a sweet show with my band and another band. our band was killing. we were about five or six times more rehearsed than usual (we like to improvise, we're lazy) and we had a bunch of great sit ins. rappers delight, i want you back, signed sealed delivered, move on up/touch the sky, soul intro/the chicken (JACO!) it was an absolute blast. my question is; we played a bunch of fresh material and people liked it, what do you do to keep material fresh and exciting so as not to play the same old boring crap?
