There is a particular kind of ambition that announces itself not through volume but through lineage, and Rootless — the Glasgow-based collective who have made a virtue of being from everywhere and nowhere at once — wear theirs like a second skin. Their new single, "Dam Mast Qalandar," takes on one of the most over-recorded, over-sampled, near-untouchable pieces in the qawwali canon — the song Nusrat Fateh Ali Khan turned into a kind of devotional Big Bang — and dares to ask what happens when you run it through a Roma fiddle and a Glaswegian postcode. The audacity alone deserves a hearing.

Some songs are sacred texts. Mariah Carey's *We Belong Together* is one of them, a millennial torch song so thoroughly canonised by karaoke bars and wedding DJs that tampering with it feels less like a remix and more like graffiti on a cathedral wall. Magumbo, evidently undeterred by questions of taste or self-preservation, has not merely tampered — he has gutted the place, rewired the plumbing, and installed a disco ball where the altar used to be.

Cole Porter, one suspects, would have raised an eyebrow at the notion of his 1953 standard being handed over to a UK producer for a four-on-the-floor makeover destined for a Pride float in Paris. He might also, being a man who understood spectacle, glamour and the occasional flagrant disregard for good taste in service of a good tune, have rather enjoyed it.

Three teenagers from Espoo have made the kind of record that makes grown men reach for their old flannel shirts and pretend they never threw away the Sub Pop catalogue. Nooa, Rasmus and Kalle, all seventeen, bring fresh energy, youthful fury and an uncompromising attitude to the grunge tradition, and the result, mercifully, sounds nothing like a tribute act fumbling through someone else's adolescence. It sounds like their own.

Three tracks, two of them recycled and one of them new, and the whole exercise lands with the unhurried confidence of someone who has stopped trying to prove anything. Amanda Emblem made her case last September with *The Wood*, a ten-track album that stretched out, took its time, and asked listeners to settle in for the long haul. This EP does the opposite. It is *The Wood* with the fat trimmed and the bones rearranged, and the surgery suits it.
