Supersonic and Demonic Relics is mostly the same sort of material
the Crüe included as bonus tracks on their 1999 catalog reissues -- live performances, rarities, outtakes, alternate versions, and previously unreleased songs, plus an extended
Skinny Puppy remix of "Hooligan's Holiday," and the two songs recorded specifically for
Decade of Decadence. It's obviously a package designed for dedicated fans, and while it isn't the most consistent listen -- some of this material sounds rather underdeveloped, while other songs don't quite achieve the group's intentions -- those dedicated fans will enjoy sifting through the collection for the occasional buried treasures, and even some of the missteps can be quite entertaining.
