"Some call them kings. Others call them gods, but one thing that everyone agreed on was that Tenacious D was more talented than the Beatles, Stones and Zeppelin combined." Those are the immortal words of "Extra"'s Maria Menounos, retelling the tragic story of the greatest rock band to ever rock, Tenacious D. Members Jack Black and Kyle Gass apparently fell on rough times after the box-office failure of their film, "Tenacious D in the Pick of Destiny." But after years in a mental hospital and "lots of drugs," Tenacious D have returned with a brand-new video and news of their third studio album, Rize of the Fenix. The new video shares the story of the lost years of Tenacious D. After a nervous breakdown, Gass spent years locked away, only to escape in hopes of reuniting with his former bandmate, Black, now going by the name "Hollywood Jack." Entitled "To Be the Best," the video chronicles D's climb back to the top of all of rockdom. In traditional Tenacious D style, the boys have some of their famous friends stop by to join in on the fun. In an interview recalling D's spectacular fall from grace, Academy Award-winning actor Tim Robbins shared his memory of Gass' battle with his demons. "Kyle couldn't take the pressure," he said. "It was no more Kyle. It was only Rage Kage." The most tragic part of the return of Tenacious D comes at the expense of Val Kilmer's life. The method actor takes a bullet fired by Gass and meant for Black, but his death was not in vain. The incident spurred the Tenacious D reunion fans have been begging for since 2008. Unfortunately, during their hiatus, both Black and Gass forgot how to rock. Thankfully, Dave Grohl, Josh Groban and two books, "Blowing F---ing Minds for Idiots" and "Impregnating Ears for Idiots," were there to help out. Rize of the Fenix will be in stores on May 15.
