Europe's award-winning band Within Temptation launched their U.S. tour this week in Louisville, KY in anticipation of the U.S. debut of The Heart of Everything, due out July 24. The first single from The Heart of Everything is entitled, "What Have You Done," and includes guest vocals by Keith Caputo, vocalist of Life of Agony.

Exposing their music to US audiences will prove to be a new chapter for Within Temptation, as they join the Hottest Chicks of Metal tour as direct support to fellow female metallers Lacuna Coil, along with Stolen Babies, and In This Moment. The Revolver Magazine sponsored tour will span throughout the US and Canada, kicking off on May 5th and running through June 6th.

You can be a part of it by joining the What Have You Done? site. Share photos, video, use the interactive tour map, plan meetups on the forums and much more.
