Give or take 2 years ago, I answered an ad and helped start a blues band (band 1). At the time, the singer and the guitarist were in a different band, and the drummer was in 2 different bands plus some projects. We hired a second guitarist, and for a while things took off. We got good gigs, opening for international (blues) acts and it culminated into an opening slot on a pretty good festival. The band of the singer and guitarist disbanded about 6 months after we started the blues band (band 1). They started a second band (band 2) got a different rhythm section, a new (and incredibly good) guitarist and recorded an album. It took off like crazy in the local blues scene, and it has led them to get loads and loads of gigs. This caused discord in band 1, between the singer and guitarist (being in band 2 ) on the one hand, and the drummer and the second guitarist on the other hand. As a bass player, I seem to fall nicely between both factions. Though band 1 has not yet officially disbanded, it seems highly unlikely that we will get together again. So the second guitarist wants to start a new band (band 3) with the drummer. I initially asked to join, but ... This quote from a recent thread seems fitting: Most of the issues and discussions that we had in band 1 (even prior to the "other band rift") stem from the second guitarist. I am pretty sure that he costs us gigs, cos he brings an entire entourage to every gig and makes sure they all drink for free. He plays too loud, is stubborn of mind and frankly, at times just not fun to play with. Technically and theoretically, though, he is very gifted. Recently my dad (who used to sing) bumped into "my" drummer, and they got to talking. The drummer jumped to conclusions and announced that my dad would be singing for band 3. I then suggested we move away from the initial "blues" idea and towards classic / symphonic rock, given that this is where his strength as a singer lie. He's just not a good blues singer. To this, Mr Second Guitarist replied saying the genre's been picked, he knows what he wants and it will be blues with some funky elements. This made me wonder what the heck I was thinking, wanting to be in band 3 with this guy. I have contacted the drummer of my former band to form a trio. Whilst he is a less good musician than what I have come to be used to, I think it will be more fun than spending more time with Mr Second Guitar, aka He Who Knows What He Wants. On the other hand I have to admit that I have already improved vastly because of his suggestions, explanations and even from the songs he picked for the (now defunct) blues band. Guess the question here is, what would you do? Join band 3 with a person you know will be a PITA to work with, or leave it and just pursue other avenues? Just to be clear, the trio thing will happen regardless of the other choice.
