Andy Allo is all smiles, holding her acoustic guitar under a small, wooden roof in the verdant climes of South Cameroon. There's no amplification; she has no band. But she does have radiant backing — via the Baka women of Bifolone, who augment her performance with their exultant vocals.

"As long as you're here/ Might as well say/ Don't be afraid/ I'm going away," Allo sings. "The one you knew/ Bid adieu/ Somewhere a long time ago." As the singer/songwriter's rendition of "Back to Africa" picks up steam, so do her accompanists, who lift up this exuberant performance with their claps and counterpoint.

In this episode of Global Spin, watch this feel-good performance straight from South Cameroon. Therein, the throng sing in exultation as they deliver this ode to the precious continent.

Allo already commands a sizable legacy. In her twenties, she was a guitarist and vocalist in Prince's band; the Purple One also co-wrote several songs with Allo and served as executive producer on her second album, Superconductor.

In her thirties, she is one of the two stars of "Upload," a Prime Video series helmed by Greg Daniels from "The Office"; the show returns for its second season on March 11.
