To borrow a line from their official Facebook bio: “If you're a fan of stripped-down garage rock, loud drums, and/or redheads, meet your perfect match in White Mystery.” Comprised of siblings Miss Alex White (guitar, vocals) and Francis Scott Key White (drums), the Chicago-based duo champions a lo-fi, DIY sound informed by the likes of Black Sabbath, Tina Turner and Led Zeppelin and makes a point of dropping albums (or in the case of 2015, a feature film) on the stoner holiday of 4/20. Reportedly named after a flavor of Airheads candy, the “raucous redheads” (as the online culture mag Traverso dubbed them) play a BYOB show at K23 in support of this year’s Outta Control, their sixth studio album. Also on the bill, Waco’s Teenage Sexx, Oakland’s Everyone Is Dirty and SA’s own Whatever?
