Osibisa, the West African high-life band from Ghana, waxed their first LP in 1971 and continues to spit them out. Their longevity can be attributed to a vibrant sound and the ability to inject humor into music. They don't allow themselves to become mired in social issues as did the short-lived but often brilliant Cymande, whose LPs were essentially political statements. Osibisa's only agenda is making good music, and if it happens to strike a political or social nerve, fine, but it's not what they're totally about. "Wango Wango" starts slow but evolves into a wicked jam that's heavy as P-Funk. Pleasant flute and trumpet riffs accent the lovely "So So MI La So." The bands' tribute to America, the floating "Sweet America," teases and tantalizes. Percussion heads will appreciate "Ye Tie Wo" and "Che Che Kule." The deepest slabs of social commentary are the thought-provoking "Sweet Sounds" and "Did You Know." All tracks were written by all or various members of Osibisa, who share production credit with John Punter.
