"Cosmosis is an electronic music project, specifically Goa Trance. Personnel originally consisted of Bill Halsey and Jeremy van Kampen for the first album: Cosmology, widely regarded as a classic in the Goa Trance genre. Subsequent albums from and including "Synergy" lean towards the less melodic but more complex PsyTrance sound, and were produced by Bill Halsey only." One of the pioneers of Goa / PsyTrance, is not extremely repetitive and includes a more melodic touch. One track from the first album and a track from his last (so far) from 2009.
