Real Name:
Ralf Müller
German trance producer.

Back in the middle of the 90’s he started his musical career in Punk and Rock bands as a trained guitar player. Later on he became more interested in Electronic Dance music and began to spin records. At this time he met Ralph Kyau, a Trance music producer for years and a pioneer in the East German Techno scene. These were his first steps toward producing his own music and together with Ronski Speed, a good friend and DJ, Rough Mullar started to build up his own studio.

In 1997 Ralph Kyau and Steven Moebius Albert founded their label Euphonic and were looking for fresh innovative stuff and new producers and so Rough Mullar was signed.
The first single "Free Love" became a small success in Germany and Switzerland. In 1999 Sonorous' "Did You Ever Dream?" E.P. was released. The title track gained airplay in many countries like Canada, Australia, Israel, Poland and Austria.

One of these E.P. tracks was an Ambient track that contains a certain vocal sample. In 2000 Sonorous rediscovered this forgotten tune and created a new more danceable version of "Glass Garden".
