[2] Cosmic Gate was formed in 1999 when Terhoeven (also known as Nic Chagall) and Bossems (also known as Bossi) decided to assemble a new project in the electronic music field.

[3] Their first single was "The Drums", followed by "Exploration of Space", "Mental Atmosphere" and their "Somewhere over the Rainbow" remix using samples from the film The Wizard of Oz.

Cosmic Gate have made many remixes for artists such as Tiësto ("Urban Train"), Ferry Corsten ("Punk"), Blank & Jones ("DFF"), Israel Kamakawiwo'ole ("Somewhere Over the Rainbow"), Svenson & Gielen ("Answer the Question") and Vanessa-Mae ("White Bird").

Over the past few years, Cosmic Gate's sound has developed and moved away from the harder edge trance through to their current, more subtle yet still driving energetic music style.
