I've been gigging regularly as a drummer for thirty-nine years and as a hand percussionist for four.
I've filled in on bass for a song here and there, but I've never gigged as THE bassist. That is, not until last night. I played hand percussion and bass last night, had a blast.
I've been working hard to become a serious bassist for about three and a half years. My long term goal was to gig as a hand percussionist and bassist in addition to as a drummer. I can now say that I have.
I have a lot more to learn, I'm purely mediocre on bass at this time. But, I have good time and locked in with the guy who filled in as hand percussionist last night.
