With two singular Bay Area bands this double bill delivers a one-two punch of rambunctious rhythm. Led by shapeshifter vocalist Zakiya Harris, Elephantine is a seven-piece Afro-eclectic combo that fuses soul, house, and hip-hop with electronic sensibilities. Featuring singers, dancers and instrumentalists, the band boasts a huge, stomping sound. Bells Atlas is a dynamic group out of Oakland that draws on highlife, hip-hop, samba, and R&B. What unites these two bands is their ability to grab ears and inspire relentless body movement.
