John Ridley describes Idris Elba as a Renaissance man; were he not so humble, he might just as easily apply the expression to himself. An Oscar-winning screenwriter for the magnificent 12 Years A Slave, he's also a dab hand at directing, producing, novel-writing and (believe it or not) stand-up comedy.

He's ferociously thoughtful, considered and intelligent too, so our latest offering is as much about sociology and politics as sound.

John's latest project is Guerrilla, made by the ever-reliable Showtime and available in full via Sky Atlantic. Staring Idris, Frieda Pinto and Babou Ceesay, it focusses on the little-known story of the British Black Panther movement in 1970s London. In addition to some rare contemporary grooves from that, you'll hear extracts from Hanz Zimmer's score for 12 Years A Slave, Waddy Watchel's bespoke arrangements for the Jimi Hendrix biopic All Is By My Side, and a spot of Carter Burwell's work on 3 Kings (which John scripted).

But in putting this episode together, we owe a special debt of gratitude to his music supervisor on Guerrilla, Sarah Bridge. Not only did Sarah provide us with hard-to-find source tracks by Britain's first ever all-black rock group Noir, she also delivered examples from Max Richter's score - including Love Song, the piece that plays under Edith's introduction.
