It's hard to believe that "Discussion" is 20 years old. Cited by none other than Marcel Dettmann as one of the most important German techno records of the 90s, it has lost none of its lustre despite the passage of time. The bass is pounding and dark, the vocals pitched down and druggy and the synths seethe with eerie intent. In recognition of its importance, Muller has commissioned a series of remixes. Claude Young drops a busy Detroit techno take,Ulrich Schnauss, one half of Beroshima, turns it into a lithe, melodic affair and DJ Rok rides a rolling techno juggernaut rhythm through its centre. Even Hacker gets in on the action with a pulsing disco version.
