After much anticipation and patience, the lineup for the Rockstar Energy Drink Mayhem Festival has been revealed.

Headlining this year's festival will be Slipknot and Slayer with a major special guest that will be announced on March 5th.  The main stage will also feature As I Lay Dying, The Devil Wears Prada, and Asking Alexandria.

According to the Mayhem website:

In 2012 the tour has upgraded the production on the festival stage and this year the Jagermeister Stage will feature a special headline set by Anthrax supported by a rotation of The Devil Wears Prada, A I Lay Dying and Asking Alexandria, along with Whitechapel, High On Fire and the Jagermeister opener. Please note that bands may vary per market.

The tour kicks off June 30th in California and runs through August 5th. There are 2 Texas dates: July 10th in Dallas and July 11th in Houston. For the rest of the dates, click here.

All I can say is "I can't effing wait to see Slipknot and Slayer".
