He studied piano with Cecil Taylor and Borah Bergman, and music and composition with Milford Graves and Bill Dixon.
His keyboard technique is something of a jazz hybrid of Cecil Taylor and McCoy Tyner, decidedly percussive but with relentlessly fast right-hand linear structure.
Blum plays with such forcefulness and rapidity that he sounds like Conlon Nancarrow's player piano rolls, interpreted via human hands, freed up into a liquid state.
[1] He is an underground legend[2] of the downtown music scene in New York, known for his explosive[3] high-voltage pianism,[4] and as a musician who aims for the very personal.
