Permanent Waves is the seventh studio album by Canadian rock band Rush, released on January 14, 1980. It was recorded at Le Studio in Morin Heights, Quebec, and mixed at Trident Studios in London, UK. Permanent Waves became Rush's first US top five album, hitting #4 on the Billboard 200, and their fifth gold selling album. The album marks a distinct transition from long conceptual pieces to a more accessible radio-friendly style; and consequently, a significant increase in record sales for the band. Both of the singles "The Spirit of Radio" and "Freewill" have continued to receive significant radio airplay since the album's release.
