Swedish reed player Mats Gustafsson's extended saxophone techniques draw from free jazz and Europe's microtonal school. Hundreds of albums demonstrate his encyclopedic knowledge of jazz, vanguard classical, and more. Gustafsson's 1992 album Mouth Eating Trees and Related Activities is an avant-jazz classic. His solo saxophone dates, including 2008's Mats G Plays Duke E and 2012's Bengt, reveal his poles of interest, while 2015's Cuts of Guilt, Cuts Deeper showcased an improvisational rock aesthetic. 2018's Timeless balanced aggression with conceptual ideas, and 2023's Their Power Reached Across Space and Time - To Defy Them Was Death or Worse was recorded with electronicist Joachim Nordwall.
