Having recently announced their split, Swedish House Mafia are releasing this compilation to accompany their farewell tour. Around a third of Until Now is their own music, as embodied by Greyhound – best summed up as John Barry meets the Chemical Brothers – and the jaunty Primark house of this week's No 1 single, Don't You Worry, Child. The rest is remixes and retweaked old hits, such as Miami 2 Ibiza, which has sprouted a soft-rock verse lifted from Dirty South's Walking Alone. All are subjected to the same heavy hand on the tiller: beats are stonkingly four-to-the-floor, singers wail, breakdowns shudder. The apotheosis is The Island, a blaring remix for Pendulum, which presumes anyone listening will be so trolleyed they won't notice its manifest lack of soul or brains. That said, it all has a headbanging urgency that induces anyone listening to tap a foot, so Until Now can probably be classed as a triumph for the band.
