A documentary titled 'No One's Disciple' about the late Rush drummer Neil Peart is set to premiere at the Toronto International Film Festival, featuring insights from Geddy Lee and Alex Lifeson, as well as tributes from Rush and various drummers. The film, which has received support from Peart's widow, aims to portray his legacy as a devoted friend and influential musician. CBC will also release a separate documentary on Peart later this year.
