We're giving away a pair of tickets to every date of this year's Rockstar Energy Drink Mayhem Festival tour (you know, the one headlined by Slipknot)! To win, head over to the Roadrunner Facebook page. There are 12 Slipknot-related trivia questions buried in our Timeline. Find them, answer them correctly, and email your answers to [email protected], with the date and city of the Mayhem date you'd like to attend in the subject line. (Transportation's not included, so pick a show that you can get to on your own.) Good luck!

Don't forget that Slipknot members will be signing copies of their new compilation, Antennas to Hell, purchased at Mayhem! For just $20, you can purchase the two-disc version of Antennas to Hell on-site, get an Antennas to Hell poster and meet members of the band.
