Temple of the Dog

Contrary to popular belief, the grunge supergroup wasn't a Pearl Jam-Soundgarden collaboration; soon-to-be-PJ members Stone Gossard and Jeff Ament formed Temple of the Dog with singer Chris Cornell as a tribute to their former Mother Love Bone bandmate, singer Andrew Wood (who overdosed on heroin in 1990). Though Eddie Vedder sings on the band's hit "Hunger Strike" as well as backgroudn vocals on a few other tracks, he's not confirmed for this reunion tour—though we wouldn't be surprised if he popped up at a few shows.
