Caress of Steel is the third studio album by Canadian rock band Rush, released on September 24, 1975, by Mercury Records. It was recorded immediately after the band concluded touring in support of their previous album, Fly By Night, and marked a development in the group's sound, moving from the blues-based hard rock style of their debut towards progressive rock. Songs such as "The Necromancer" furthered Rush's advancement into narrative-driven, fantasy-based compositions, while "The Fountain of Lamneth" was their first prog-rock "epic" to span an entire side of vinyl. Other tracks like "Bastille Day" and "Lakeside Park" became staples of the band's live setlists.

Rush was a Canadian rock band that primarily comprised Geddy Lee, Alex Lifeson (guitar) and Neil Peart. The band formed in Toronto in 1968 with Lifeson, drummer John Rutsey, and bass guitarist/vocalist Jeff Jones, whom Lee immediately replaced. After Lee joined, the band went through several line-up changes before arriving at its classic power trio line-up with the addition of Peart in July 1974, who replaced Rutsey four months after the release of their self-titled debut album; this line-up remained intact for the remainder of the band's career.
