Di Costanzo has released numerous records on established record labels. His first single for Aphex Twin's Rephlex label, "Scharlach Eingang" (1994), published by Warner / Chappell Music, was sufficiently accomplished that the British music magazine NME ran an article claiming that Bochum Welt was another of Aphex Twin's alter egos.
Di Costanzo's first album on Sony Music Japan, "Module 2 / Desktop Robotics" collecting his first recordings, was followed by a double CD Rephlex release Robotic Operating Buddy.
"GOOD PROGRAMS (to be coloured in yellow)” his more recent album (2014) was released by BMG / Rephlex records.
In addition to releasing his own music, Di Costanzo has worked with Thomas Dolby's Headspace and Beatnik Inc., the Hollywood companies that completed multimedia productions for S. Spielberg, David Bowie and others.
