Casper unites his expertise in jazz and classical music through the use of electronic drums and other sounds. His crossover into electronica and trip-hop informed grooves has been chiefly inspired by Jazzanova, Cinematic Orchestra, DJ Shadow and Bonobo. He employs his primary instruments (piano, Rhodes and analog synthesisers) to create rich textures and improvised parts, then blends in a seamless mix of electronic and acoustic drums.
