4. Temple of the Dog
At the height of the Grunge era, two of its biggest bands decided to join forces as a tribute to a fallen friend. Conceived by Soundgarden's Chris Cornell in honour of recently deceased Mother Love Bone singer (and his roommate) Andrew Wood, Temple of the Dog would only record one album before disbanding. But the union of Pearl Jam and Cornell would produce a hit in the instantly catchy "Hunger Strike," which perfectly matched PJ lead singer Eddie Vedder's signature baritone with Cornell's soaring vocals. Though the full band never played most of the album live, Cornell continued to perform "Hunger Strike" with both Audioslave and his solo band.
