There's nothing that beckons to a well trained ear quite as much as classic trance. Especially back when Ferry Corsten and Tiesto would collab under the name Gouryella, not only does their work bring back a nostalgic feel that trance fans know and love, but it brings an uplifting melody mixed with fantastic vocals to top it all off. Walhalla is essentially the best of what we remember from early trance, the late 90's were filled with these types of vocal trance tracks and yet this one still always ends up sticking out to me.
Be sure to give it a listen below and if you havent already be sure to follow Ferry Corsten on SoundCloud for all of his releases, and keep up with him through Facebook and Twitter as well to see where in the world he is play.
