Hey Col9, that's a good enough band there, especially if the drummer's ok!
I'm sort of a new player but moved on a bit as I've been playing for about 3 years, and I've been going to various jams for about 18 months. I have to admit I find nearly all but the simplest blues-based jazz a little beyond me, although I'll happily toot a chorus or two out front, and I really enjoy riffing with other horns in the background. I think in general I'm progressing on the jazz stuff, though. But, when it comes to blues, r'n'b or soul/funkier stuff, I'm well away, probably as being 51 I grew up on the 60's and 70's music, mainly rock etc. Like Frank, I love the jazz and would love to be able to play it more confidently, but i have more of a feel for the 'simpler' forms.
I have my ear to the ground in terms of looking for a band, and I'll happily play as the lone sax-player or part of a section in a blues/soul vein; what I'd really love to do is play in a band based around an organ-player, as I love the sound and feel of jazzy/bluesy organ.
So, from the perspective of a relative newcomer, I'd say to all you new starters that getting out and playing with other people is a good thing , whether it's as part of a jam or in a more formal band setting. Many more advanced musicians are very happy to let new players have a blow, and many are also very encouraging.
Cheers, Bob
