Three 6 Mafia could be making an appearance in Pittsburgh as early as next month — to be deposed in a lawsuit by a fan who was injured at one of their concerts.

Ramone Williams claims in his lawsuit that he was beaten as the rap group sang "Let's Start a Riot" at an Aug. 26, 2003, concert at a now-defunct Pittsburgh nightclub.

Williams, then 19, alleges that before the song was over, he was thrown to the floor, hit with a chair, stomped on and kicked in the face. His injuries included a fractured jaw.

His lawsuit claims the club neglected to warn patrons or protect them from violence and should not have permitted an underage customer to enter.

It also accuses the rap group of failing to warn of violence, for inciting the audience and failing to stop the violence.

Williams' lawyer, James E. DePasquale, told the Pittsburgh Post-Gazette in a story for Friday's editions that he expects Three 6 Mafia to answer subpoenas by the end of April to be deposed for trial, which could begin by November.

Three 6 Mafia, from Memphis, Tenn., won the Oscar for best original song this year for "It's Hard out Here for a Pimp," from the film "Hustle & Flow."

John E. Hall, the group's Pittsburgh lawyer, declined to discuss pending litigation, but has said the group members deny all the accusations.

Three 6 Mafia group members include Jordan "Juicy J" Houston, Paul "D.J. Paul" Beauregard and songwriter Cedric Coleman.
