The main pseudonym of Richard D. James, one of the leading electronic musicians in the 90's, the prime innovator of the IDM movement, and the founder of Rephlex records. He has no experince in musical theory, and has built most of his instruments by himself. He makes a colossal amount of e-music in many different styles, from slow, mellow ambient pieces to harsh, drilling noise sequences.
"That's a fine IDM piece, Jonny. not Aphex Twin, but still good."
