A childhood in Memphis, a classical conservatory education, composition and electronic music study with Stockhausen in Cologne; a passage through the New York minimalist sphere with Terry Riley, Reich, Glass; having a window opened onto the world's music and a new approach to the trumpet via vocal master Pandit Pran Nath; a questioning and deconstruction of the European dichotomy between classical and popular, sacred and sensual; a pioneer of digital transformation and sampling—all of this led to Fourth World—the unique blend which Jon has described as "worldly music" to underline a more subtle equation at work and discourage the simplistic labeling of "world," "jazz," "classical," "minimal," or "ambient."
