OK, disc 2 features 4 tracks: the 7" edit, and remixes by Kris & Dave, Thomas Fehlmann, and The Soulcatcher. You know the 7" edit is good - heck, you wouldn't be reading this if you didn't. The remixes are great too.
Kris & Dave's remix is the stand out track. It's like a fast, dark, evil trance song. Tres cool. Thomas Fehlmann's mix is slower and more in the spirit of the original. Again, this is good. Soul Catcher's remix is faster and trancier, but not dark like Kris n Dave. It's more upbeat and stuff. It would probably satisfy the PLUR-spewing raver kiddies.
Order this now. It's great. Plus, it comes in a nifty box to store both it and disc 1, and a sticker!
