The singer was found dead on his tour bus in Medina, Minn. Scott Weiland & The Wildabouts were scheduled to play at the Medina Ballroom on Thursday night, but the show was cancelled.
Weiland's cause of death is unknown. The singer (born Scott Richard Kline), who grew up in Ohio and California, had famously struggled with substance abuse for years, which had eventually led to his firing from Stone Temple Pilots. Formed in 1989, STP became an alt-rock powerhouse in the mid-'90s, with five albums released between 1992 and 2001 and hits like "Plush," "Interstate Love Song" and "Vasoline."
After departing Stone Temple Pilots, Weiland formed Velvet Revolver as a supergroup with former Guns N' Roses members Slash, Duff McKagan and Matt Sorum, along with Dave Kushner. The band released two albums before tensions rose and the members split in 2008.
Weiland last was a part of the Stone Temple Pilots in 2013, re-forming with the group until he was unceremoniously fired via Internet message. STP has since recorded and toured with Linkin Park's Chester Bennington.
Scott Weiland & The Wildabouts' debut album, Blaster, was released in March. Weiland also released three solo albums between 1998 and 2011.
Weiland married Jamie Wachtel, a Los Angeles-based photographer, in 2013. It was his third marriage.
