Very cool. I was turned on to the music of Conlon Nancarrow a zillion years ago in college, by a music professor. Nancarrow is often called one of the fathers of electronic music, but he never understood it. After all, he never wrote for a synthesizer or sequencer in his life! Nancarrow's music is very dense and intellectually intense, but it's also very emotional, full of humor and love. It's not (always) cold the way a lot of process-driven composers like Schoenberg were cold.<p>Nancarrow's own player pianos were customized with steel and leather hammers to get an even more powerful sound. The recordings in his studio are amazing, but I imagine it must have been far more intense live.
