The second phase of his career began with the formation of his early fusion group Osmosis in 1967. Known at the time as a strong bop altoist with a sound of his own developed out of the Charlie Parker style, Mariano began to open his music up to the influences of folk music from other cultures, pop, and rock. He taught again at Berklee, traveled to India and the Far East, and in the early '70s settled in Europe. Among the groups Mariano has worked with have been Pork Pie (which also featured Philip Catherine), the United Jazz Rock Ensemble, and Eberhard Weber's Colours. Charlie Mariano's airy tones on soprano and the nagaswaram (an Indian instrument a little like an oboe) fit right in on some new agey ECM sessions and he also recorded as a leader through the years for Imperial, Prestige, Bethlehem, World Pacific, Candid (with Toshiko Akiyoshi in 1960), Regina, Atlantic, Catalyst, MPS, CMP, Leo, and Calig, among others. ~ Scott Yanow, Rovi
