Scott Weiland, the grunge rocker best known as the frontman for Stone Temple Pilots and Velvet Revolver, has died. He was 48.
Weiland died in his sleep in Bloomington, Minnesota, according to a statement on his Instagram and Facebook accounts. His agent Tom Vitorino confirmed the star's death to NBC News.
Weiland, who had been dogged by substance abuse problems throughout his career, had been due to perform with his band the Wildabouts on Thursday night.
Bloomington Police said they were called to a hotel "on a report of an unresponsive male in a recreational motor vehicle" at 8:22 p.m. (9:22 p.m. ET) on Thursday. He was later declared dead.
Only hours earlier, pictures of Weiland performing at Britain's Reading Festival in 1993 and with Aerosmith's Steven Tyler at Madison Square Garden three years later were posted to his Twitter account.
Weiland achieved fame as the lead singer of the Grammy Award-winning Stone Temple Pilots, whose hits include "Interstate Love Song," "Plush" and "Vasoline."
The band broke up in 2003 and Weiland went on to front Velvet Revolver, whose members included former Guns N' Roses guitarist Slash. Among that group's hits was "Fall to Pieces."
The Stone Temple Pilots eventually reunited in 2008 before breaking up again in 2013.
