The Chemical Brothers were one of two bands closing Glastonbury this year – the other being The Who. Similarities between the rock juggernauts and the dance pioneers are more abundant than you might think, both feature two aged men standing motionless on the stage apart from the occasional rhythmic head-nod, both fill arenas with people slightly older than they’d care to admit, and most importantly both are labelled with the unfortunate term “legacy act”.

Born in The Echoes is the eighth studio album of Tom Rowlands and Ed Simons’ genre-creating dance act. It opens well with the simmering and sinister ‘Sometimes I Feel so Deserted’ before moving onto big-beat romp ‘Go’. The technical ability of the duo is without equal and they embarrass EDM producers around the world with the ease with which they drop a brain-frying chorus. In fact, the problem with the record is not its ability to compete with the young pretenders who have moved the dance genre forward since The Chemical Brothers’ heyday; the problem is their own back catalogue.

Take ‘I’ll See You There’. This is a good track; Rowlands and Simons seamlessly meld the unhinged mania of an acid trip into stomping beats and shattering chorus, making it seem like big-beats and psychedelia were made to be together. The reason they do it so well is because they’ve done it already – on ‘Setting Sun’ a track off 1997’s Dig Your Own Hole. Similarly, getting Q-Tip to feature, his hip-hop pedigree complimenting the jittery basslines and colossal choruses perfectly, would seem like a stroke of genius. And indeed it was – the first time. The rapper also appeared on one of the duo’s biggest tracks, ‘Galvanise’. These moves would have been revolutionary had they not done them already.

But should that be held against them? They’re taking inspiration from other songs, but those songs are theirs in the first place. After all, no-one is criticising Pete Townsend for wind-milling his guitar like he has been for the last 50 years or denouncing Bob Dylan for his nasal mumbling. Perhaps they are a “legacy act” now, not quite as ground-breaking as they once were, but there was an eye-watering amount of people losing their shit at Glastonbury watching the duo and they know exactly why. The Chemical Brothers perfected a revolutionary formula long ago, and even if they’re going through the paces now it doesn’t make it any less thrilling.
