I was invited to join an established folk band for a rehearsal last night, with a view to joining them. I've not played upright properly for a few months, and just before I found the G string has failed in some annoying buzzy way (notes on the G string buzz horribly, the same notes played on the D string are fine). Anyway, I was about first there, and set up with my trusty Crush 25B amp. There was accordion, violin, octave mandolin, clarinet, bodhran and washboard. The set list was a mixture of Morris dance tunes, Irish folk tunes and Klezmar. All went well - I kept it simple, mostly improvising, root-5'ing the chords with an occasional run on chord changes.
