DJ AM, raised as Adam Goldstein in Philadelphia, was critically injured last night in a South Carolina plane crash that killled four people and also seriously injured Travis Barker, former blink 182 drummer, the Associated Press reports. Goldstein (on the left in the photo) and Barker perform together as TRVSDJ-AM and had played a free concert near Columbia, SC. The pair are both being treated at a burn center in Augusta, Georgia, according to the AP report. The small Learjet crashed shortly after take-off, killing two passengers and two crew members, whose identities have not been released, the National Transportation Safety Board told the AP. Goldstein was scheduled to be in Philadelphia this Wednesday to pose for a group photo of more than 100 Philadelphia DJs as part of the first annual Philadelphia DJ Day. He was also scheduled to perform Thursday night at Pearl (1904 Chestnut). We expect the injured DJ to miss both local appearances as he recovers both physically and emotionally from the tragic airplane crash.
