Rob Mazurek is an American electro-acoustic composer, cornetist, improviser and visual artist living in Chicago, Illinois.
Mazurek was born in 1965 in Jersey City, New Jersey, and played trumpet and cornet in high school in Naperville, Illinois. He first learned the foundations of improvised music while studying jazz theory and practice with David Bloom at the Bloom School of Jazz in Chicago, eventually working with other Chicago musicians like Kenny Prince, Robert Barry, Jodie Christian, Lin Halliday and Earma Thompson.
In 1996 Mazurek formed the longstanding Chicago Underground Collective with guitarist Jeff Parker and drummer Chad Taylor, a unit that ranges in size from duo to orchestra. The Collective earned Mazurek the attention of the Windy City’s underground community at the turn of the Millennium, resulting in high-profile collaborations with other genre-defying artists like Gastr Del Sol, Jim O’Rourke, Sam Prekop, Stereolab and Tortoise.
