Input: Question: Are both of the academic institutions that Gussow attended in the Ivy League? Passage:Around this time Gussow, a Princeton graduate and English M.A. student at Columbia University, first saw Magee and his trio performing on the corner of 114th Street and Broadway. (Gussow relates the story in his 1998 blues memoir, Mister Satan's Apprentice.) Gussow, a guitarist and harmonica player whose performing experience had previously been limited to a handful of high school and college bands, was galvanized by the encounter. After dropping out of grad school, Gussow spent several years as a part-time street performer in New York and Europe. Gussow's transformation from an academic to a blues player was facilitated by lessons he took from his mentor, New York harmonica virtuoso Nat Riddles, who had performed and recorded with Larry Johnson, Odetta, and others, and by his acculturation into the jam session life at Dan Lynch, a storied East Village juke joint.
