The Hudson Valley is overflowing with music festivals these days. Some are uber-hip, featuring national acts, artisanal food and drink. Others, like the Rondout Music Festival, are meant more for mass entertainment, with the kinds of bands that you don’t need to be familiar with to enjoy (mostly because they typically play cover songs). Performing acts include B Boyz, Jungle Love, Gottasee, DJ Eddie Parker, SoulOMusic, and Vince Fisher. Get on the dance floor or spread out on a picnic blanket. Rain date is the following Sunday.
