Harmonix and MTV Games have announced that a four pack of tracks from “rock stars” Spinal Tap, along with a three pack from Evanescence, will be added to the Rock Band Music Store next week for the Xbox 360 and Playstation 3.

Three of the four Spinal Tap tracks (“Back from the Dead,” Rock ‘n’ Roll Nightmare” and “Warmer Than Hell”) come from the band’s new album Back From The Dead (The Label Industry Records/A2M) also being released on June 16. The fourth track in the new Rock Band package will be “Saucy Jack,” a song St. Hubbins wrote about the life of Jack the Ripper, which was previously only available on the band’s website.

Grammy Award-winning rockers Evanescence also make their Rock Band debut next week with a three pack of the band’s greatest hits. “Bring Me to Life,” from the band’s 2004 multi-platinum debut album, Fallen, “Call Me When You’re Sober” and “Weight of the World,” from 2006’s The Open Door, will all be available in the Rock Band Music Store beginning June 16th.
