Velvet Revolver and lead singer Scott Weiland have parted ways in a bitter war of words that saw the four founding members of the band accuse him of erratic behaviour and a lack of commitment to the group.

Weiland was equally critical of his bandmates, calling the group "a handful of discontents who at one time used to call themselves a gang.

"The truth of the matter is that the band had not gotten along on multiple levels for some time," he said in a statement issued Wednesday.

After playing together Tuesday in Amsterdam, Velvet Revolver's management company issued a statement on behalf of the non-singing members saying they were dropping Weiland, 40, from the group.

Slash and two other former members of Guns N' Roses, bassist Duff McKagan and drummer Matt Sorum — along with second guitarist Dave Kushner — brought Weiland in as the Velvet Revolver lead singer after he left Stone Temple Pilots.

Weiland has been seen publicly feuding with Sorum and he has a history of heroin addiction.

He is free on a $40,000 US bond after being charged with driving under the influence of drugs. He was arrested on a Los Angeles freeway ramp in November.

Weiland said all members of the band have had stints in rehab and called references to his erratic behaviour "a blatant and tired excuse to cover up the truth."

Weiland declared the band "dead in the water on March 20 in Glasgow" — a reference to a statement he made on that date that Velvet Revolver was on its last tour.

Weiland plans to rejoin his former Stone Temple Pilots bandmates this summer for their first tour in seven years.
