The innovative guitarist and producer Michael Brook was born and raised in Toronto. While studying electronic music and the arts at the University of Toronto, he met trumpeter Jon Hassell, with whom he later toured; through Hassell, Brook also was introduced to minimalist composer LaMonte Young, under whom he studied Indian music. A period working as the house engineer at producer Daniel Lanois' famed Grant Avenue recording studio led to a tenure playing guitar with the Canadian pop band Martha & the Muffins during the late '70s; at the same time, Brook also met Brian Eno, guesting on the 1980 Eno/Hassell collaboration Fourth World, Vol. 1: Possible Musics. In 1983, he also played on Harold Budd's Magic Realism.
