Wolfgang Düren played guitar in various local bands in the 1970's, but soon became more and more interested in electronic music. From 1978 he was a roadie for Tangerine Dream for three years, traveling the world with them and programming their sequencers. In the 1980's he worked for the Hamburg musician and inventor Wolfgang Palm and his company PPG (Palm Products Germany), which is primarily responsible for the development of the revolutionary digitally controlled PPG-Wave. In 1988 Wolfgang Düren became self-employed and founded the company Waldorf Electronics, with which he continued to use wavetable synthesis after the closure of PPG in 1987. Hiphop artist Eminem used samples from Wolfgang Düren's track 'Eyeless Dreams I' for his song 'Evil Twin' from the 'The Marshall Mathers LP 2' album from 2013.
