Curious times, these, when the latest advance in dance music is a subtly tweaked revamp of deep house. This is the basis of Digital Disco, where clean lines and theoretically soulful vocals are enhanced by the latest laptop dub techniques and four-to-the-floor beats are gently mutated by the pops and clicks of micro-electronica. Occasionally, cheese triumphs over invention. But the highlights are lovely, especially contributions by tricksy Montreal wonderkid Akufen and the peerless Vladislav Delay (using his Luomo pseudonym), who adds real depth and guile to music habitually dismissed as glossy and vacuous.
