Though the band has since released four more albums on Atlantic Records, this double-disc set was the original, definitive Rush anthology, spanning the band's entire 15-year, 16-album relationship with Mercury Records. In fact, this set is virtually perfect, clearly illustrating the Canadian power trio's evolution from Cream/Zeppelin enthusiasts into a groundbreaking, progressive hard rock unit. Acclaimed classics like "Finding My Way," "Fly by Night," "A Passage to Bangkok," "Closer to the Heart," "The Spirit of Radio," and "Tom Sawyer" are interspersed with less-well-known, but equally vital tracks like "Bastille Day," "La Villa Strangiato," "Limelight," "Subdivisions," and "Red Sector A" to paint a literal moving picture (pun intended) of the band's career. As a testament to its excellence, Mercury was incapable of improving upon this package when releasing the nearly identical Retrospective six years later on two separate CDs.
