It seems a number of PSB fans are decrying Disco 4 as a bastardisation of the Disco Series concept, in that this time round it's mostly a non-stop mix of club tracks they've done for other artists. Which is an odd sentiment really, given that Disco 2 is generally considered PSB's weakest release and Disco 3 was not non-stop remix at all but a tactical electro-comeback after the less than rapturous reception of Release. So, to be fair, the Disco concept is fair game, and this outing number 4 is certainly better than 2 and conceptually purer than 3. If there's an issue it should be that no big PSB fan will not own most if not all of this music already. But altogether here, in non-stop mix format, in true-to-form fabulous packaging, you have to acknowledge the impressive line-up of weighty legends Bowie, Madonna and Yoko Ono with the cool of The Killers, Atomizer and Rammstein. As is so often asked with PSB - who else in pop music could do this kind of thing?
