My current group has some issues at guitar. I could write a ten page rant about it. Honestly it's all the same stuff that anyone here has dealt with that's played in amateur bands. I'm trying to dump the guy. The guy makes at least one catastrophic (usually two) mistakes a gig. I could be playing a flawless gig up to that point, but then I start really steaming. Then I typically start making mistakes of my own, albeit not huge ones. Still, they are mistakes that I don't typically make. It takes me a few songs to really calm down and get back to being focused. I guess it's also worth noting that I do the booking, web stuff, business, sound, scheduling, etc. in addition to being the bass player. I feel like I have the right to get pissed off with as much as I have invested in the project, but I don't like it effecting my playing. Do you guys have any pointers on recovering during a set from stuff like this quickly (other than getting a new guitar player or going on medication!).
