I've been in this band for 6 months now and I'm having regrets. We've had 4 gigs and each time the guitar player becomes this other person.Pratice is fine, but at gigs he always invites friends and trys to come off like this big shot to impress them. He's insulted the drummer (who is very good) in front of people, He friends call out songs for him to play and he's says " I would, but they don't know it" so the drummer and I look like a couple of dicks.The kicker at the last gig he just start playing a song that we never played before. I walked over and said "what are you doing?" I was told "when you play with me you have to be ready for anything." I've talked to him about all of these things and he says fine at practice' but the gigs are another thing. I already know what to do, but Like many, venting is therepeutic
Just remember you don't have to fire him. You could leave and take everyone else with you but him. Dirty trick but hey....
