Second-line brass-band slink meets brooding junkyard R&B and percussive West African guitar in the hands of the Oakland combo with a rich host of inspirations drawn from across the atlas and the skills to knit them all into a cohesive whole. The weekly party at Elbo Room celebrates 18 years this weekend, with resident DJs Sep, J Boogie, Maneesh the Twister and Vinnie Esparza, plus a live special live performance by J Boogie’s Dubtronic Science.
