The guitarist and lead singer(who also writes most of the material) insists on changing things up without warning. By this, I mean he capos his guitar to change the key of a song without telling anyone, he goes from one song to another without warning during sets, making odd medleys without warning, and even starts into songs hes just written without telling us or letting us hear them before we preform. He doesnt want a set list either, he just wants to play what hes felling at the time. To this point, I havent fallen flat on my face, but I know its coming. At some point, hes gonna change it up and Im gonna get lost and have to stop or butcher a performance. Ive talked to him about it and he said, "You can hack it", which really isnt the point. I'm starting to feel underprepared for the 1st time since I started playing bass and I dont like that feeling. This is the only band Ive ever played with. Am I just being a wus? Is this typical or even acceptable behavior for a frontman? Leaving isnt an option I want to explore, but I might have to get in his face at the possible loss of a long and productive relationship. Have any of you experienced this sort of scenario? How would you deal with this?
