Last year FACT went loopy for a song by mysterious Ghanaian rapper Ata Kak.

‘Daa Nyinaa’ was recorded some time in the late ’80s or early ’90s and dug up a decade later by ethnomusicologist Brian Shimkovitz, who runs the Awesome Tapes From Africa blog. Last year it was given a subtle disco-leaning edit by producer Noema and released as part of a compilation called African Shakedown – although that record is pretty hard to come by already.

Amazingly, this week BBC Radio 4 broadcast a 30-minute documentary tracing Shimkovitz’s search for Ata Kak, which took him around the world at huge personal expense. Ata Kak and the Crate Diggers also features interviews with Andy Morgan, former manager of desert bluesmen Tinariwen, Miles Cleret from the excellent Soundway Records, and Ghanaian highlife legend Ebo Taylor. That’s what you pay your licence fee for, eh?

Listen back via BBC iPlayer – it’s available for six more days. Hat tip to Luke Abbott for spotting this one.
