The musical brains behind the act Gouryella are the influential Dutch producers and DJ's Ferry Corsten and Tijs Verwest aka DJ Tiësto.

The act name Gouryella is a reference to the hereafter of the Aboriginals. The first same name single "Gouryella" is a phenomenal piece of trance, with a strong song structure and a wicked drive. Inspired by the big success of "Gouryella", Ferry and Tiësto hit the studio together again and came up with their more commercially orientated follow-up single, entitled "Walhalla". Complemented with excellent remixes by Hybrid and Armin van Buuren "Walhalla" became again an international success and entered the UK single chart at a #27 position.
