I've played bass for more than a dozen years, in one local band as well as professionally in a few short gigs--though for multiple reasons I question the judgment of the people who hired me for that.
I've played guitar for 14 years, including with several small-time bands.
I've played mandolin for 10+ years in a few local bands.
I joined flashband when I moved to DC to meet musicians. Now it's been a few years but I still enjoy meeting new people to play music with--and my last band split up so I wouldn't mind finding a new one to gig with.
