Thomas Ankersmit (born 1979 in Leiden, The Netherlands) is a musician and installation artist based in Berlin. Initially an improvising saxophonist, his activities expanded to include live electronic music and installation pieces based on architectural acoustics and infrasound. He has been performing solo and in collaboration with other artists such as New York minimalist Phill Niblock, Kevin Drumm, Jim O’Rourke, Gert-Jan Prins, Borbetomagus and Alvin Lucier since 1998. Since 2003, Ankersmit most frequently collaborates with Niblock and Milan-based electroacoustic improviser Giuseppe Ielasi.
His saxophone work focuses on the abstract, timbral extremes of the instrument, combining sustained streams of intense multiphonic sound with acoustically amplified micro-events occurring inside the instrument.
