Invisible System 2011

After five years as an aid worker in Ethiopia Dan Harper recorded an innovative dance-fusion album with musicians from that country. The record was called Punt and it was the start of an ongoing project called Invisible System. He's just released his second album and as well as strong Ethiopian influences it's clear that this unconventional musician has fallen in love with another African nation, Mali. Nick Atkinson spoke to Dan from a studio near his home in the English West Country.
