Approaching their sixth album, the Chemical Brothers may have felt, like James Murphy did on LCD Soundsystem’s Losing My Edge, that ‘the kids’ are coming up from behind. With young pups Justice and Digitalism currently white-hot in dance circles, Tom Rowlands and Ed Simons have a lot to prove if they are to live up to what their album title claims. They do so brilliantly on Do It Again, a subterranean romp with east-London hipster Ali Love questioning his hedonistic pursuits; and the Klaxons hint that there will be life after rave as the new Blur on All Rights Reversed. On an album already steeped in psychedelia, it seems a given that The Pills Won’t Help You Now will be about a bad batch of ecstasy; this Midlake collaboration is emotionally taut and heartfelt. With their reputations at stake, the Chems have conjured their most brilliant work since 1999’s Surrender. Are the boys losing their edge? Not a bit of it.
