The Devil's Staircase is an international group of musicians who play rock inspired by math and science. But they don't play math rock. Ideas from nonlinear dynamics, fractals, cellular automata, and astronomy inspire compositional forms, but don't tell the band what to do. The group features Luis Nasser (Sonus Umbra), Tim McCaskey (Sonus Umbra, Might Could), Mattias Olsson (Änglagård and others), Ramsés Luna (Luz de Riada, Cabezas de Cera), Aaron Geller (Might Could), and Edgar Arrellín Rosas (Luz de Riada, Cabezas de Cera).
