SCOTT THOMSON is a trombonist and composer who lives in Montréal, having moved from Toronto in 2010. He plays in established groups in many styles, and prizes ad hoc improvising as a way to meet many creative people. He has studied with Roswell Rudd, Jean Derome, Eddie Prévost, and John Oswald. Scott is one of the founders of the Association of Improvising Musicians in Toronto (AIMToronto), and co-directs the AIMToronto Orchestra, which was formed for a project with Anthony Braxton in September 2007. While in Toronto, Scott was the artistic director of Somewhere There, a venue for live creative music that he founded in 2007. Scott has composed a series of site-specific pieces that he calls ‘cartographic compositions’ for mobile musicians and audiences in unconventional performance contexts, including works for the galleries and corridors of the National Gallery of Canada and the Art Gallery of Ontario.
