Alto saxophonist Nathanael Su – better known as Nat Su – is committed to transparent and expressive jazz and is the author of a groundbreaking book on jazz harmonics. Born in 1963 in Bülach (ZH), he studied music at the University of Music and Performing Arts in Graz and at Berklee College of Music in Boston.

He has been actively recording and performing since 1987, inter alia with Irène Schweizer, Franco Ambrosetti, Omri Ziegele, his own Nat Su Trio and Nat Su Quartet. He is the director of the International Hashva Orchestra, a quintet of representatives of younger American jazz. In 1997, he received a composition commission for the quintet from the Canton of Zurich, and two years later he was awarded the Werkjahr grant by the City of Zurich. Nat Su teaches saxophone, ensemble and jazz theory at the Lucerne School of Music. He plays in several jazz formations, notably in duo with jazz pianist Jean-Paul Brodbeck, and with the Straymonk Quartet.
