Re: Guitarist rant
I've had those exact problems with different guitarists from different bands and needless to say I'm not in a band with them anymore.
I'm not friends with any of them either sadly, but it kind of made me realize they treated my friendship the same way. (Flaky when they had girlfriends and pissy attitudes)
I'm sure your situation is unique though and I'm not telling you to ditch your friends because being in a band is less fun without friends...
Good luck and I hope things work out!
