Adam "DJ AM" Goldstein was buried in a private ceremony for family and close friends, with guests including Travis Barker.

The Blink-182 drummer attended the small service on Wednesday — six days after the celebrity DJ's death — which began shortly after 3 p.m./PT at Hillside Memorial Park and Mortuary in L.A., according to Us.

Guests included Ocean's 11 star Scott Caan and DJ Jazzy Jeff. Goldstein's girlfriend Hayley Wood was also in attendance, according to RadarOnline.

The service began in the mortuary and moved outside around 4 p.m. where a car procession followed the hearse to the back of one of L.A.'s most prominent Jewish cemeteries for a 15-minute burial. Barker, wearing a dark, pin-striped suit, sunglasses and slicked-back hair, tossed dirt on the coffin of his close friend.

A memorial at the Hollywood Palladium is also scheduled for Thursday at 7 p.m. "The format of the evening will be in the style of an open 12-step meeting," the invitation reads. "Adam's friends both from his life in recovery, as well as those from other areas of his life, are welcome."

Goldstein, who notably battled drug addiction, was found dead in his New York City apartment Aug. 28 after an apparent relapse. A crack pipe was found in the apartment, and nine undigested OxyContin pills were found in his body.
