Call it ambient post-doom. Call it alchemic psych-rock, only without all those annoying freeform guitar freakouts. Call it “pure spirits by ritual dismemberment.” Either way, Black Math Horseman is Sera Timms (bass/vocals), Ian Barry (guitar) Bryan Tulao (guitar) and Sasha Popovic (drums). They are from Los Angeles. Their debut album, Wyllt, was recorded and produced by desert guru Scott Reeder (Kyuss, Unida)
