What an EPIC line up as Slipknot, Lamb of God & Bullet For My Valentine comes to Red Rocks Amphitheater on Wednesday 19th August 2015! With their forceful guitar rhythms and experimental NU metal sound, Slipknot are back! And even more exciting, with a brand new album in the makings along with new masks to be exposed on tour. You can expect big things, including never heard before. Get ready to ROCK!
