On that front, 7th Moon doesn't disappoint a bit. "Mbua-A-Matumba," one of two extended story-songs, builds to a meticulously arranged climax, vocal counter-rhythms and likembe marbling patiently around one another; a similar, even drummier explosion occurs on the ecstatic "Drowning Goat (Mbuji-Mayi)." Even the electric guitars shimmer, peeling small figures (and recalling Baltimore guitartistes Ecstatic Sunshine) on "Mpombo Yetu" and elsewhere. Only the mostly a cappella "Tshitua Fuila Mbuloba," though gorgeous, fails to evoke the gliding, otherworldly quality of fish in the moonlight — or whatever other transliteration you'd care to invent.
