Sonar was founded by Dirk Ivens and employed the help of Patrick Stevens in 1996. The aim of Ivens's and Stevens's project was to "remind [one] to working machines, the soundscapes to droning planes." . Both Ivens and Stevens have continued work on Sonar to this date, but also devote time to their other projects. Ivens is most well known for his solo-effort, Dive, as well as his stint in Klinik and Stevens for his project Hypnoskull. Please see the individual pages for more information on both artists.
