Hard on the heels of the announcement of their election to the Rock and Roll Hall of Fame, Rush will publish their first iBook, in celebration of the 1976 album 2112 on Tuesday. (Next Friday is 12/21/12.) The electronic book will present previously unpublished photos, black and white ink art and pencil sketches for every comic book cell, and preview music for the remastered 2112 with three bonus live tracks. It will also contain a 40-page comic book, expanded artwork, liner notes and  lyrics.
