New Orleans legend Trombone Shorty is only 36, but he’s been performing in bands of various sizes for more than 30 years, blowing his horn with jazz, funk, rock, and hip-hop artists and showcasing a versatility few can match. His Voodoo Threauxdown is returning to SummerStage this summer and is the embodiment of New Orleans’ musical melting pot, a showcase for several generations of the city’s talent. Tank and the Bangas fuse funk, soul, hip hop, rock, and spoken word poetry, while Big Freedia is arguably the most high-profile practitioner of New Orleans bounce, a high-energy strain of hip-hop born in the city’s housing projects. Cyril Neville and his old band the Meters loom large over the rest of the bill: While Neville is performing as “The Uptown Ruler,” founding bassist George Porter Jr. is performing the legendary funk band’s music with Dumpstaphunk, which features Cyril’s nephew Ivan Neville, whose father was the Meters’ founding keyboardist. They’re joined by the eight-piece brass ensemble the Soul Rebels, who were given their name by Cyril after opening for him at the Uptown New Orleans venue Tipitina’s.
