TRIBUTES HAVE POURED in for former Stone Temple Pilots and Velvet Revolver frontman Scott Weiland who died early his morning.

The popular singer died in his sleep while on a tour stop in Bloomington, Minnesota, in the US, according to an official Instagram post.

The cause of death is unknown at this point.

This evening, Associated Press reports that police in Minnesota say they found cocaine in the bedroom of the tour bus.

A “small quantity” of the drug was found and a man travelling with Weiland was arrested. He hasn’t been charged.

On tour

His current band Scott Weiland & the Wildabouts had been scheduled to play a show in nearby Medina.

Weiland’s wife, Jamie Weiland, also confirmed his death to the Los Angeles Tribune.

“I can’t deal with this right now,” she said, sobbing. “It’s true.”

Eulogy

Leading rock musicians have lead the tributes to the popular and influential singer.

In a eulogy posted on the Smashing Pumpkin’s website, frontman Billy Corgan said that Weiland was a one of the “great voices of our generation” along with Kurt Cobain and Alice in Chains’ Layne Staley.

“As any fan, I find myself reflecting on what I do have in my own treasure chest: in scarce moments where Scott and I spoke as contemporaries or competitors, and got to know each as people other past the footlights and shadows we were so busy casting to the world.”

Meanwhile, some of Weiland’s former Velvet Revolver bandmates took to Twitter to express their grief:

While Wheatus and Aerosmith’s Joe Perry also paid their tributes:

Weiland rose to fame as the frontman 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, the supergroup that featured former members of Guns N’ Roses, including guitarist Slash and bassist Duff McKagan.
