The author discusses SLANT , an improvisation-based project he coconceived, recorded and performed on tenor saxophone in duo with pianist and new music specialist Richard Valitutto. The project deconstructs sound worlds such as late nineteenth-century Romanticism, avant-garde/free jazz, microtonal spectralism and southeast European rural music. Drawing on George Lewis's systems of improvisative musicality, the article analyzes SLANT through the lens of sociomusical experience. The author shows how Afrological, Eurological and other systems of musicality participate together, manifesting in dialogical improvisative music-making that emerges from multiethnic and multicultural histories of improvised music.
