AS Jonny Greenwood has admitted, musicians schooled in rock engage with world music at their peril. Yet the man whose uncommon musicality has periodically elevated Radiohead from bog-standard to tilting at greatness is not your average rocker, his bent for adventure having led to collaborations with Polish composer Krzysztof Penderecki and scoring such films as There Will Be Blood.

Here his questing continues, this time via a foray into the world of qawwali – Sufi devotional music – in new compositions by the Israeli musician Shye Ben Tzur and accompanied by an ensemble of Indian musicians.

It’s no great surprise that the resulting two-CD set is a ragged, riotous wonder in which the key elements of dholak (hand drum), brass, strings (sarangi, kamaicha) and voices soar and sink like the bubbles in a broiling gumbo. Among the panoply of pleasures there is immeasurable beauty (the elongated, keening intro of Hu), a diversion into the avant-garde undergrowth (the near nine-minute Kalandar) and several arresting choral pieces, notably the mantric Eloah and the joyous techno minimalism of Roked.

Mercifully free of so much as a hint of rock tropes, Junun is a revelation which will revive even the most jaded palate.
