Slipknot are on board to headline next year's Sonisphere Festival.

According to Kerrang!, the metal group will perform during the Knebworth Park set July 8-10.  The band released the following statement:

"We're looking forward to spending our summer in Europe.  This tour is about us and our fans. It's about celebrating the life of our brother, Paul and his legacy.  The door is neither open nor closed.  This tour is about burning down that door. See you [next]summer."

This will be the first show since the tragic death of bassist Paul Gray back in May of this year.
