DJ Andy Kershaw is to return to BBC radio with a new music series that ties in with BBC One show Human Planet.
He will host Music Planet, which BBC Radio 3 calls its "most significant and ambitious world music project ever".
Kershaw and co-presenter Lucy Duran will travel around the world to record "extraordinary music" in "isolated locations" visited by the BBC One show.
The presenter had been off the air for two years, after a series of well-documented personal problems.
These culminated in the DJ being jailed in 2008 for breaking a restraining order which banned him from seeing Juliette Banner - the mother of his two children.
He was later given a suspended six-month sentence for again breaching a restraining order.
Human Planet is described by the BBC as a "landmark natural history series", filmed in about 80 locations and exploring "man's remarkable ingenuity and success as a species".
The companion series will visit Switzerland, Peru, Madagascar, Kenya, Greenland and Mali to explore people's musical traditions.
Highlights include the sounds of the Bat People of Papua New Guinea, the mystical voices of the shamans of Mongolia and Greenland's "katajja"', a vocal contest between two women with songs that involve throat singing and imitating animal cries.
In a statement, Kershaw, 50, said: "I am thrilled to be back on Radio 3 working again with a team of bright, imaginative, enthusiastic, people who also happen to be dear friends.
"Nowhere on earth is safe again from my attentions. So far we have - literally - hacked through mountain jungles to bring Music Planet listeners extraordinary music from some of the world's most isolated locations.
"And I cheerily risked incineration at a rocket festival in Thailand to take our Radio 3 audience into the fiery thick of the action."
Human Planet and Music Planet will air on the BBC next year.
