I've recently engaged in something that I am now of the belief all should try at some point. It's a:
1) Theatre production that doesn't have a pit, but utilizes a
2) Small combo (guitars, drums, trumpet, fiddle) that
3) Plays with no written music whatsoever and
4) It's all done for free, volunteered.
Of course, I'm probably a little late on some of this, I'm sure others have run into this before, but I've got to say, what a great experience! You get a chance to play in a really different, live environment; to listen and jam with guitars on new songs, training your ears, chops, fingers, brain; and an opportunity to give the gift of music. I find myself really enjoying it, not being paid never a factor, and it's really a load of fun. Just thought I'd share this experience with you all, and maybe get some thoughts/ similar experiences.
