Nowadays I play the banjo and the mandolin. I like to try to play most of the music I listen to on the instruments, so I end up fooling with classical, rock, jazz and bluegrass a lot. I'm yet to make an ambient/trance track, but I'm working on it.
Thanks to my girlfriend, I now listen to the local college rock station a lot (KTCL in Fort Collins, Colorado), and consequently I have increased my exposure to Hootie, Joan Osborne, Soundgarden, Dada and other heavy-rotation artists. They don't play enough Pink Floyd for my liking.
My all-time favourite people to listen to, though, are Bela Fleck, Tony Trischka, and J.S. Bach.
One day I'll scan my CD covers and have my pants sued off, just 'cos I like the sound of having well-dressed lawyers take my pants off.
