I've been playing trombone since the 4th grade. In high school I played with the University of Bridgeport Prep Division Jazz band, and performed at the Montreux Jazz Festival with it.
While I was in the Navy I kept my trombone with me on the ship, and sat in with lounge and jazz bands in many of the ports of call we visited.
I always had a corporate 'day job' after college, but I also worked as a full time musician in New York City for a little over 18 years; playing society affairs, weddings and such, before moving with my family to Israel.
I now play for my own enjoyment, and have been invited to join a local amateur orchestra when I retire in 4 years (my travel schedule is too hectic to commit to the rehearsal schedule now).
I don't know if there is a connection between PTW riding and music. But a disproportionate number of my musician friends also ride two wheels.
