by Michael G. NastosWith every passing year, pianist Omar Sosa continues to define what contemporary world music can be. Each effort is quite different than the previous one, while the bright colors, timbres, and elements of his Cuban-based music are elevated higher and higher. In his restlessness to find further truth and beauty, there's a calm serenity and unabashed confidence in his vision and personal musicianship. For Afreecanos, Sosa uses artists from every portion of the globe except Australia and Canada, though some have lived there, too. They include fellow Cubans Orestes Vilató on timbales and flutist\u002Fsaxophonist Leandro Saint-Hill; trumpeters Bill Ortiz (U.S.A.) and Stephane Belmondo (France); Africans Mola Sylla, Fanta and Baba Sissoko, and (from Morocco) violinist Mohamed Soulimane -- as well as Brazilian vocalists and the American-based bata player Michael Spiro. As you can imagine, this melting pot of rhythmic, vocal, and instrumental sound blends into a potpourri that makes refreshingly new music within ritual and traditional frameworks. There are many highlights: the heavy staccato-laden worldbeat groove blues of Ollú, the jazz-oriented horn charts and singsong or harder-edged but lighthearted D'Son and Tres Negroes, the effortless and funky African-derived Tumborum, the flute-fronted oceanic-cum-Yoruban Light in the Sky, and the sorrowful, more question than answer-oriented Why Anga?, for the late conga player Miguel Angá Diaz, who played with Sosa up until his untimely passing. You'll hear straight African chants, spirit songs, and a ballad or two, the 21-stringed kora featured on the entirely beautiful Iyade, and an occasional piano interlude from Sosa. As time goes by, with his music featuring fully developed progress-oriented themes, you notice less of Sosa as an individual voice and more in an image as a team player or village chieftain. In fact, the group singing is more prevalent than his individual playing. Omar Sosa continues to make brilliant music where the natural and spiritual meet the contemporary. He continues to set the bar further up into the stratosphere, and one can only imagine how far he's going to reach. This is a major artist on the international scene who all should be paying close attention to.
