On Elephantine, his new Northern Spy album, Cairo-based Maurice Louca guides a 12-piece ensemble through a 38-minute masterwork that might best be described as panoramic. Elements of free improvisation, Sun Ras cosmic jazz, gorgeous Arabic melody, trancelike African and Yemeni music and minimalism meet in his wholly unique compositional vision. Louca also makes vital contributions on guitar and piano, and inspires stirring performances from a global lineup.
