The band's style changed over the years, from a blues-inspired hard rock beginning, later moving into progressive rock, then a period in the 1980s marked by heavy use of synthesizers, before returning to guitar-driven hard rock at the end of the 1980s. Rush were known for their musicianship, complex compositions and eclectic lyrical motifs drawing heavily on science fiction, fantasy and philosophy. Rush ceased touring at the end of 2015, and Lifeson announced in January 2018 that the band would not continue, which was cemented by Peart's death from glioblastoma, a type of brain cancer, on January 7, 2020, at the age of 67.

The trio regrouped in 2001 and released three more studio albums: Vapor Trails (2002), Snakes & Arrows (2007), and Clockwork Angels (2012). Rush continued to record and perform until 1997, after which the band entered a four-year hiatus due to personal tragedies in Peart's life. The band's popularity continued throughout the 1980s and 1990s, with albums charting highly in Canada, the US and the UK, including Permanent Waves (1980), Moving Pictures (1981), Signals (1982), Grace Under Pressure (1984) and Counterparts (1993). Rush achieved commercial success in the 1970s with Fly by Night (1975), 2112 (1976), A Farewell to Kings (1977) and Hemispheres (1978). After Lee joined, the band went through several line-ups 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. The band formed in Toronto in 1968 with Lifeson, drummer John Rutsey, and bass guitarist/vocalist Jeff Jones, whom Lee immediately replaced.

Rush was a Canadian rock band that primarily comprised Geddy Lee (bass guitar, keyboards, vocals), Alex Lifeson (guitar), and Neil Peart (drums, percussion, lyricist).
