Rye Rye got the party started in the desert. M.I.A.’s 20-year-old protégée lit up the Sahara stage at Coachella in a neon-colored top, cutoff shorts adorned with patches, and rainbow army boots as she dove into her lively set. She gave festivalgoers a taste of her debut album Go! Pop! Bang! by performing her single “Bang” and the M.I.A.-assisted “Sunshine.” Pharrell (“Shake, Twist, Drop”), Bangladesh, and Tyga have contributed to the project, due later this year.
