Cameron, 62, announced his decision Monday on social media. He saluted his Pearl Jam band mates, which include two former San Diegans — lead singer Eddie Vedder and lead guitarist Mike McCready — bassist Jeff Ament and guitarist Stone Gossard.

The drummer did not give a reason for his departure after nearly 30 years from the Grammy Award-winning rock group.

Cameron first joined in 1998 as a temporary replacement for Jack Irons, playing on a long tour before making his studio debut with the band on 2000's "Binaural."
