If you like beer with your bluegrass, head over to Dulono's on Lake Street. But if you don't mind standing and coffee is your fuel of choice, the most beguiling boinging can be heard at the Homestead Pickin' Parlor's "Jam Sessions." Here, music shoppers and anonymous local pickers alike bring their banjos, fiddles, dobros, spoons, and everything else to make a beautiful racket while customers comb the CD racks. Stop in any night or weekend afternoon (except Monday) and catch an open-ended, unscheduled bluegrass, flatpicking, folk, or Cajun jamboree. If you bring your instrument and join in, you'll get a cookie.
