Fun neighborhood place where there is almost always a few people jamming. Get supplies for your acoustic instruments (strings, picks, etc), take lessons of all sorts, or come to a community song circle led by a professional musican. Don't miss their Annual Folk Festival, generally held in July - check their website for this year's date.
They have lots of concerts here that showcase true local talent. You will often need tickets in advance, though, so call ahead.
