Celebrate America for the second weekend in a row with the fourth annual Great South Bay Music Festival at Shorefront Park in Patchogue.
The three-day festival of "American-themed" music and arts has expanded again, adding some jam bands and gospel music to the mix and giving festivalgoers a chance to make some music of their own at a Korg-sponsored Musical Petting Zoo and a "Guitar Hero" contest in the Looney Tunes Tech Tent.
"We'll have rock, jam bands, folk, blues and gospel music all day," says Jim Faith, the festival's co-producer. "It's a safe, affordable place to spend the day."
But there's a lot of talent among the festival's 47 performers earlier in the day. Don't miss:
