There's more to Armin van Buuren's sound than uplifting trance and soaring toplines. On “Great Spirit”, van Buuren, Vini Vici and Hilight Tribe evoke ritual chants over stomping drums, and on “Dominator”, he offers a storming update to Human Resource's techno classic. Then there's his clever remix of “Let It Go”, which is sure to bring out the inner child in Frozen fans everywhere.
