This annual three-day event draws thousands of bluegrass fans for concerts, dances, workshops, vendors, impromptu jam sessions, and good old-fashioned bluegrass music. Best of all, it’s indoors! This year’s Saturday night headliner is the Becky Buller Band, led by Buller, a Minnesota native who plays a mean fiddle. Get a head start on the musical madness with an early bird jam session on Thursday night. Tickets available daily ($20 Friday, $25 Saturday and $5 Sunday) or $40 for a weekend pass. Saturday night headliner is $23 separately. Crowne Plaza Minneapolis West, 3131 Campus Drive; 800.635.3037; minnesotabluegrass.org.
