Seriously, I thought being able to play more than one instrument would earn respect/credit/whatever from band members but this doesn't seem to be the case. Two nights ago saw me get into a full-on screaming match with my guitarist over this very issue which almost became a serious punch-up. Long story short, I play guitar, bass and also piano. In the band I'm currently in, a small rock-ish band, I initially begun playing bass only, but eventually began playing the guitar and piano in the practice room, and then eventually at gigs too. My lead singer and bandleader thinks this great as it's expanded our setlist by a massive amount and means that should he wish to practice with me alone, we can have something of a melody to work with. Problem is that this seems to have rattled our guitarist to the point of the situation in the first paragraph. He seems to actively hate the fact I am playing the piano at all in the band, and has in the past complained it's 'pushing him out' or that 'it's a distraction' at gigs or some other ridiculous statement. I hold him under suspicion of at least once trying to sabotage my keyboard too, although it would be massively difficult to prove this. I've tried my hardest to make him understand that a) I'm still first and foremost a bassist for the band before anything else and b) I'm trying not to push anyone out, and least of all him, as I have a great deal of respect for his skill on the guitar. Any ideas what to do?
