Since 1994 Stef Lopazz, also known as LOPAZZ, has been part of the Heidelberg based HD800 team; he also runs the multimedia label 800achtspur, and is renowned as a film composer and Mix-Mastering-Engineer, having written, produced and engineered many internationally acclaimed records and films. In 2001, he had success with Redagain P when they remixed the Miami Vice & Magnum, P.I. themes; then, in 2003, Lopazz's self-titled EP was released by Output Recordings, followed by the singles 'Blood' and his first bona fide club hit ‘I Need Ya’. Its success led to Lopazz remixing Germany's biggest pop act Xavier Naidoo, while techno legend Sven Väth snapped up ‘I Need Ya’ for his Sound of the Fourth Season mix CD. Stefan's relationship with Berlin-based Get Physical Music began when he was commissioned to remix Chelonis R. Jones' 'I Don't Know'. The label went on to issue Lopazz's own vocal track ‘Migracion’, which was subsequently remixed by Chilean producers Luciano and Ricardo Villalobos. Releases for Pokerflat, Cocoon and Compost Black Label followed, along with remixes and productions for the likes of Isolee, DJ T, M.A.N.D.Y., Matthew Dear and Imagination.

Tiefschwarz are a German house group consisting of brothers, Alexander "Ali" and Sebastian "Basti" Schwarz, which formed in Stuttgart in 1996. Peter Hoff, who runs the Benztown studios in Stuttgart, joined later, and completed the first Tiefschwarz production team. Their name means "deep black" in German, and is a combination of the brothers' surnames, and their love of deep house.
