This year’s Edgefest in Toronto on July 12th is sure to be a summer favorite, with such acts as the reunited Stone Temple Pilots, Linkin Park, the Sam Roberts Band and the Bravery. STP is also slated to perform at Columbus, Ohio’s Rock on the Range fest on May 17th. Reports suggest that the heavy metal road show that is Ozzfest will potentially morph into a two day non-touring event in Dallas, TX, with the titular Ozzy Osbourne as the main attraction. The festival is facing additional competition this summer from the Rockstar Energy Mayhem Tour, which touts Disturbed as its headliner.
