Saturday's Vibes lineup was a mixed group of artists ranging from Dweezil Zappa's "Zappa Plays Zappa" project kicking things off. They never fail to interpret Frank Zappa's extremely complex and involved brand of musicality with sincere adherence to authenticity and nuance. Mickey Hart Band got the afternoon going with new vocalists that fit the project well. Headliners Primus and Sound Tribe Sector Nine are undeniably the strongest headliners as far as high energy goes. Killer day, good times.
