In 1999, successful Dutch artists Ferry Corsten and Tiësto joined forces to create the trance partnership of Gouryella. To highlight their importance in the trance scene at the time, there were 20 separate CD releases of the 4 Gouryella tracks from 9 different labels. Incidentally, the name of Gouryella comes from the Aborigine word for Heaven. Gouryella is known to have released six tracks: Gouryella, Gorella, Walhalla, In Walhalla, Tenshi and Ligaya.
