A concert featuring cult Canadian duo Zeds Dead was shut down on Saturday (01Dec12) after a spate of drug overdoses.

At least four fans were hospitalised after falling ill at the Electric Factory in Philadelphia, Pennsylvania.

According to The Philadelphia Inquirer, the teenage gig-goers had overdosed on an unidentified drug.

Zeds Dead never had a chance to perform before the concert was scrapped. They instead moved the show to the Lit Ultra Lounge.
