The composer Mario Diaz de Le�n, who creates vivid canvases for acoustic instruments and electronics and draws from influences including black metal, is in residency at the Stone this week. Musicians, including the flutist Claire Chase, perform works by Mr. Diaz de Le�n on Tuesday at 8 p.m.; the lineup at 10 p.m. includes what is billed as "demonic possession, apocalyptic visions, serialized death metal sound collage" and some of his "most extreme music."
