Matumbi, a pioneering British reggae band formed in 1971, recorded under different names such as 4th Street Orchestra, and their album Leggo! Ah-Fi-We-Dis, praised by Steve Barrow and Peter Dalton, is considered a remarkable representation of their talent and a significant reissue of a UK roots reggae gem, with original member Dennis "Blackbeard" Bovell showcasing his deep understanding of the local sound system scene and producing tracks that rivaled the output of their Jamaican counterparts, including notable covers and outstanding original compositions.
