Nick Oliveri, former bassist for Queens of the Stone Age, was arrested last July for felony domestic violence against his ex-girlfriend, and also charged with several felonies for resisting police and possession of cocaine, methamphetamines, and a fully loaded rifle.

TMZ now reports that Oliveri today pleaded not guilty to all charges, which included "two counts of possession of a controlled substance with a firearm, two counts of possession of a controlled substance, and one misdemeanor count of resisting, obstructing or delaying a peace officer." He still faces a potential sentence of up to 15 years. A pre-trial court date is scheduled for April 13.
