Very few people in music are willing to take chances these days. Too bad for them. Here is an album and a composer which take risks beautifully. Argentinian bassist Gustavo Gregorio blends jazz, latin, and other core genres with Conga, Tango, Milonga and other rhythms to create a new breed in flavor and atmosphere: Mambonga. Well received in the marketplace and lauded by some of Japan and South America's most respected latin music press, Mambonga defines itself as a piece that's as daring as it is pleasant to listen to.
