Once referred to by Duke Ellington as the “Maharaja of the keyboard,” Oscar Peterson was one of the greatest and most influential musicians of all time. This exuberant and affectionately crafted documentary from Canadian filmmaker Barry Avrich (David Foster: Off the Record PSIFF 2020) mixes archival footage of Peterson, both in performance and interviewed, with enthusiastic and revealing present-day testimonials from his family, colleagues and students, offering an invaluable comprehensive portrait of both the man and his music. Fans of other recent jazz biography docs Miles Davis: Birth of the Cool, Chasing Trane: The John Coltrane Documentary and What Happened, Miss Simone? will revel in this peek behind the keys at an equally important and inimitable musician, who hailed from Canada but still faced the same racism as his American contemporaries as a touring Black artist.
