So, I started playing with this jazz combo a month ago. I was recruited through a friend of a friend to cover for this kid that went off to school. The recruiter and the BL both said that it was a little jazz combo. They led me to belive that it was a more urbane/soulful take on the standard improvisational jazz. I got in after a two hour sit-in. I started worrying in rehearsal #2, when I couldn't get the drummer to quit stopping the song to worry about arrangement bits that are on a recording that I'd never heard. They looked offended when I suggested that we play the thing through, with mistakes and simplifications, and fix the arrangements after. Then, the BL handed me a CD of songs to learn. I could probably play them, but Stevie Wonder and Prince covers with a sax section aren't what I think about when I think about a jazz combo. It's not my style at all, and those guys do these complicated arrangements sometimes that require flurries of notes and acrobatic slaptastics that are just not extant in my current chops. Not that I couldn't learn, but there's another problem as well. I kinda don't care for the music. Eeep! I'm a little bit of a traditionalist and am a converted DB player besides, so I didn't grow up with or listen to much of this smooth/soulful jazz before. I'm also outside my usual community with this project. I brought two more standard-ish tunes to rehearsal #3. One was rejected up-front, and the other was a "well, let's do the set list first, then we'll get to it". It was an OK rehearsal, but I had to cut it short when playing such complicated stuff for such a long time (3h) torqued my forearms so badly that my fingers stopped obeying my brain. I've taken 4 days off (from anything that can make any kind of music) already and it still feels like my arms are swollen like the Michelin man. I know that it's bad position and improper mechanics and overplaying and not drinking enough water and the position of sunspots and every other reason in the book, but the fact remains that these guys expect an awful lot, even though I was really clear about my would-rather-not-be-slaptastic chops. Rehearsal #4 is coming up in a couple hours, but I already called off 'cause of the arms. I'm not *against* this kind of music, but I don't have it down in any way, shape, or form. There are gigs in a month, so the issue is getting urgent. I'm a bass player, after all, so I can fake quite a lot, but that's not gonna fly for long. And I still don't really like the music very much. So, here's the real question: Do I keep going for the upcoming dough, or drop before we get any deeper?
