Stone Temple Pilots announced on their website they are postponing 12 dates on their much-anticipated reunion tour. Though the announcement didn't specify a reason for the postponement, it comes just days after the band's frontman Scott Weiland went off on a tirade at the band's Houston, Texas stop. The band reportedly took the stage an hour after the opening act left the stage, and Weiland offered up a series of profane musings about his in-ear monitors, his past drug use, and his thoughts on grunge. Listen to Weiland's rant below.
