Come dressed up in your spookiest attire for The Rock Steady’s free Halloween turn up — Ghoulish Gala — courtesy of promoter Mike Melero (aka DJ Bobby Peru). Rising producers D33J and Karman, who are both based in Los Angeles, top the bill and will perform atmospheric, maximalist beat sets with glitchy sound palettes that evoke early videogame soundtracks. The lineup also includes Aquacure, the new, melancholic electro pop project that features James Laurence of well-known East Bay producer duo Friendzone. Swerve, a DJ duo composed of Neto 187 and So What, and Kawasaki Papi of the MoreVibes crew will serve up high-energy DJ sets made up of obscure internet rap gems, hyphy and post-hyphy slaps, and top forty remixes. If you’re looking to dance the night away on Halloween, Ghoulish Gala will be the spot. Costume suggestions: one of Drake’s “Hotline Bling” girls, a ghost-riding ghost, or Gucci Mane’s ice cream tattoo.
