Klesmer, interesting. The closest I've come to that is the Bottle Dance in "Fiddler on the Roof," which I've performed many times. The whole show is almost like a long clarinet concerto.
I mostly play community symphonies. You can search "Oakland Civic Orchestra" on Youtube if you're curious. I play musical shows also, but not a lot of that lately. For shows, I need to double on other winds, flute, oboe, sax etc.
