South African mindbenders BLK JKS create a multivalent, 360-degree view of Johannesberg Now: Afro-jazz riffs segue into tribal rhythms, which swagger through street-level sociology before exploding into hardcore bursts of noise, kwaai kwaito beats, and addictive rock hooks. Prepare yourself for a dizzy blend of up close, freaked-out, kind of-not-quite-like-anything-you’ve-heard-before music. This performance will be prefaced by a short Q&A with the band.
