Spinning traditional music into modern anthems is nothing new for producer-guitarist Michael Brook. In the past, he's recast the voice of the late Pakistani Qawaali singer Nusrat Fateh Ali Khan and the Armenian duduk of Djivan Gasparyan. This time, he takes the gentle tribal hymns and chants of Tanzania's Dr. Hukwe Zawose and turns them into a throbbing groove for a transglobal nightclub of the imagination. Zawose's multitracked voices and plaintive kalimba melodies are embraced by Brook in a techno-noir jungle that includes ethereal harmonies from Zap Mama singer Marie Daulne, horn sections that echo the kalimba themes, and guitar and bass that supercharge the rhythms. Brook infuses Zawose's music with a structural drama, a sense of journey and transition that makes tracks like "Haliko Chijende/Let's Walk" an urban African symphony and "Mbeleje/Sweet Deceiver" a surreal swirl. Assembly is far removed from the more traditional and pastoral sounds of Zawose's previous Realworld album, Chibite. Zawose may have lost his innocence, but the music still retains a joyous exuberance.
