Stefan Schwander, known as Antonelli, has produced electronic music in Düsseldorf since the mid-1990s. He works under multiple pseudonyms—including A Rocket in Dub, Repeat Orchestra, and Harmonious Thelonious—and collaborates with artists like Jörg Burger (as Pop Up). His style blends techno, disco (notably Giorgio Moroder), new wave, dub, abstract electronica, and African music.
