Although I'm a fervent admirer of Depeche Mode, OMD, New Order and Human League, I have to admit that this album tops anything I own from the eighties, even Depeche's masterpiece "Black Celebration". I think I must have listened to this cd a thousand times, and think I'll never get tired of listening to it. These songs were constructed with such perfection! and it's the debut & farewell album by this great german Industrial-Techno-Pop group (I'm not taking in account the later album "1-2-3-4", because it didn't feature the original group). "Duel" is one of those classic songs that stick to you forever, with gorgeous vocals by Claudia Brücken, and just the same can be said of the rest of the cd, especially "Dr. Mabuse", a wonderfully dramatic song, and "P Machinery". Do yourself a favour and be introduced to the definitive techno-masterpiece of the eighties, and it deserves ten stars!!!
