They transform their roots, combining their own free jazz and punk aesthetics with elements of Ethiopian music, soul, funk and noise, and re-work album-oriented material by jazz icons, John Coltrane and Duke Ellington. The group features Mats Gustafsson on tenor, soprano, baritone, and bass saxophones - with Ingebrigt Haker Flaten on electric bass and Paal Nilssen-Love on drums.
