The stacked lineup includes 17 bands, with headliners like veteran jam bands ALO and the Mother Hips, folk and bluegrass groups Hot Buttered Rum and David Nelson Band, and funky acts Royal Jelly Jive and the Soul Section. Other highlights include the guitar raffle, Lagunitas brews, specialty foods and kids activities.
