Since the mid-1980s, Simon Wernli has stood at the vanguard of the electronic music movement under his artist moniker DJ S.I.ONE (also recognized as DJ S.I.ØNE or DJ S.I.One). As a genuine pioneer of Swiss rave culture, he blends timeless trance anthems, driving hard trance, and dynamic techno into an unmistakable sonic signature.

A defining milestone arrived in 1996: with the legendary anthem "SPACEPLANET 303", Simon created an enduring classic (his primary project is officially written as SPACEPLANET in one word, though frequently titled Space Planet on compilation releases such as the Tunnel series). In 1996, the track became the soundtrack for the official Zurich Street Parade video. To this day, he remains a staple of the Street Parade, notably commanding the spectacular "WE ARE UNITED" Love Mobile.

His discography and collaborative endeavors span prestigious publishers and record labels including EMI MUSIC Publishing, Clone 2.1 Records, Drizzly Records, TBA Switzerland, Phonag Records (featuring the acclaimed release Pulsar), K-Tel, Sony Music, BMG Ariola, and the legendary ecosystem of Tunnel Records with cult compilation series such as Tunnel Trance Force, DJ Networx, and Tunnel Goes Ibiza. Across his entire release history, Simon Wernli has contributed to projects that have achieved estimated cumulative global sales of over 5 million records.

DJ S.I.ONE takes immense pride in his formal honors: alongside his induction into the Nature One Hall of Fame (since 2010), following his featured main-stage performances at the cult festival, he was appointed an official Honorary Member of the Association R.A.V.E. (Swissrave Vinyl Archive) in 2026—recognizing his decades-long dedication to preserving authentic Swiss vinyl and club heritage.
