The bewitching grooves of singer/guitarist Leni Stern’s Sa Belle Belle Ba brilliantly fuse Western and African musical idioms. Building upon the breakthroughs on her acclaimed 2007 release Africa, Stern once again taps into the rich culture of Mali in tandem with such master musicians as oud player Brahim Fribgane and vocalist Ami Sacko. Sweltering rhythms and incantatory lyrics give “Babakar,” “Smoke’s Risin’” and “Born Bad” an otherworldly power. Echoes of American funk and blues can be heard in the serpentine flow of “Nan Jeya” and the title track. The caressing, lullaby-like “Sera” and the string-draped ballad “Now I Close My Heart” work equally well in a softer strain. Stern’s acoustic and electric-guitar work displays their trademark precision and grace on the slow-boiling “Souma Chamon,” among other numbers. From the chant-like “Madoumba” to the Middle Eastern-accented “Yakhal Bi Khali,” Stern and her collaborators embrace a wide swath of sonic terrain. The spell-casting “Namu” makes the mystical content of the album’s songs clear.
