Burlington-based Mellow Yellow may not be a big-name band at home, but, as Dan Bolles discovered in March when he sailed with the group, they’re a hit at sea. The psychedelic tribute outfit plays every year on cruise ships and has developed quite a following in the process. Their gigs back in the Green Mountain State are few and far between, but not to be missed if you’re into tie-dye and peaceful protest. Head down to Castleton on Tuesday for masterful renditions of hits by the Beatles, Janis Joplin and other classic favorites.
