This is the recurring 80s tribute festival at the Old World Biergarten in Huntington Beach, a German restaurant and beer garden that transforms into a shrine to the decade of big hair and bigger choruses. Across the year it runs themed editions (hair metal, new wave, and more), packing the biergarten with tribute bands and a crowd that came to relive it. It's SoCal's quirkiest, most local festival tradition, equal parts concert and Oktoberfest.
