Cameroonian sax player and composer Manu Dibango broke through to an international audience in 1972 with his afrobeat hit, Soul Makossa. The infectious drive on this dance classic came from the happy meeting of big-band American soul and Cameroon's dancehall makossa sound. So influential was the track that there were famously nine versions of it in the Billboard charts at one time; Michael Jackson even quoted it in Thriller. Thirty years on, at the grand age of 70, the "Lion of Cameroon" still presides over the freshest, funkiest melting pot for African and western music.

Dibango has collaborated with everyone from Herbie Hancock to Fela Kuti, and his live shows reveal a wealth of global material. In the intimate setting of Ronnie Scott's, he and his quintet are able to explore subtle sounds and textures, fading in and out of African polyrhythms, calypso, salsa and reggae grooves. Manu strolls around the band with his white sax, superbly relaxed, coaxing solos from his young pianist Julien Agazar, and punctuating proceedings with a few well-chosen notes of his own. Occasionally he opts to play vibraphone, the instrument he features heavily on his recent "B-Sides" album of remixes. Always smiling, often chuckling, Dibango radiates sunshine whether he's trading jazz licks or singing close harmony. By the time he asks his audience to participate, no one can resist.

He's ably supported on this visit by a band equally at home in African music and jazz. Bassist Noël Ekwabi guides the quintet through evocative arrangements that complement Dibango's characteristic rasping sax and liquid-gravel singing voice, leaving it to the unmistakable figure of Dibango himself to carry the audience. It has been said that without him world music would be 50 years behind. It should be added that he is possibly the world's grooviest septuagenarian, and he shows no sign of letting up.
