For the second year in a row, the festival features a terrific lineup of world, rock, pop, and reggae artists, including the Wailers and Black Uhuru. Look for San Diego’s Tribal Seeds, a rock-infused reggae group that has shared the stage with Jack White and the Red Hot Chili Peppers. Local Long Beach bands open the party, and there will be plenty of food and liquid refreshment for a fun and affordable way to groove through Labor Day weekend. More information.
