The Robinson Brothers and The Black Crowes are being sued by their drummer, Steve Gorman. Filed on Wednesday to the Los Angeles Superior Court, Gorman is suing for unpaid royalties.

“For more than five years, my attorneys and I have made repeated requests to review the Partnership’s books to confirm the accuracy of royalty payments and my share, but Chris and Rich have consistently ignored my rights under the Partnership Agreement,” Gorman said in a statement. “I regret that it has come to this, as I remain incredibly proud of the music we created as a band, but their conduct has left me with no choice but to ask a court to order them to give me this information, which I’m entitled to under our partnership agreement and the law.”

Gorman originally left the band in 2001 but returned to the group after a four-year hiatus in 2005. He claims he was short-changed during the reunion era. You can read the full story at rollingstones.com.
