Scott Weiland, best known as the lead singer for Stone Temple Pilots and Velvet Revolver, was found dead on Thursday night at the age of 48.

His rep said in a statement that Weiland passed away in his sleep while on a tour stop in Bloomington, Minnesota, with his band The Wildabouts. "At this time we ask that the privacy of Scott’s family be respected," the statement concluded.

According to multiple reports, Weiland was found unresponsive on their tour bus at around 9 p.m., and the band's scheduled show at the Medina Ballroom was subsequently canceled. The cause of death is not known, though Weiland has had a rather storied history of substance abuse, with multiple arrests and trips to rehab.

Dave Navarro was the first fellow musician to respond to the news of Weiland’s death, tweeting, “Just learned our friend Scott Weiland has died. So gutted, I am thinking of his family tonight … so, so sad.”
