Permanent Waves is the seventh studio album by Canadian rock band Rush, released on January 14, 1980, through Anthem Records. After touring to support their previous album, Hemispheres (1978), the band began working on new material for a follow-up in July 1979. This material showed a shift in the group's sound towards more concise arrangements and radio-friendly songs, though their progressive rock blueprint is still evident on "Jacob's Ladder" and the nine-minute closer "Natural Science." Bassist/vocalist Geddy Lee also employed a more restrained vocal delivery compared to previous albums. Permanent Waves was first of seven studio albums that the band recorded at Le Studio in Morin-Heights, Quebec with production handled by the group and Terry Brown.

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.
