HomeMusicReview: Bruno Råberg Bruno Råberg “Ascensio” (Orbis Music) Bruno Råberg’s Boston jazz ensemble slides fluidly between traditional, structured jazz and more free approaches. All is subdued and melodic in the final listening, the point being to entertain the listener, not challenge. Bruno Råberg’s bass holds up the acoustic, instrumental jazz here. The horns of Phil Grenadier (trumpet) and Allan Chase (saxophones) provide the main melodic elements. Crisp, swinging drums are courtesy of Marcello Pellitteri.
