Background: Rush was a Canadian rock band composed of Geddy Lee (bass, vocals, keyboards), Alex Lifeson (guitars) and Neil Peart (drums, percussion, lyrics). Forming in 1968, the band went through several configurations until arriving at its longest and most popular line-up when Peart replaced original drummer John Rutsey in July 1974, two weeks before the group's first United States tour. Rush is known for its musicianship, complex compositions, and eclectic lyrical motifs drawing heavily on science fiction, fantasy, and philosophy. The band's musical style has changed several times over the years, from a blues-inspired hard rock beginning, later moving into progressive rock, and including a period marked by heavy use of synthesizers.
Context: Rush started to deviate from its 1980s style with the albums Presto and Roll the Bones. Produced by record engineer and musician Rupert Hine, these two albums saw Rush shedding much of its keyboard-saturated sound. Beginning with Presto (1989), the band opted for arrangements notably more guitar-centric than the previous two studio albums. Although synthesizers were still used in many songs, the instrument was no longer featured as the centrepiece of Rush's compositions. Continuing this trend, Roll the Bones (1991) extended the use of the standard three-instrument approach with even less focus on synthesizers than its predecessor. While musically these albums do not deviate significantly from a general pop-rock sound, Rush incorporated traces of other musical styles. "Roll the Bones", for example exhibits funk and hip hop elements, and the instrumental track "Where's My Thing?" features several jazz components. This return to three-piece instrumentation helped pave the way for future albums, which would adopt a more streamlined rock formula. The transition from synthesizers to more guitar-oriented and organic instrumentation continued with Counterparts (1993) and its follow-up, Test for Echo (1996), again both produced in collaboration with Peter Collins. Up to this point, Counterparts and Test For Echo were two of Rush's most guitar-driven albums. The latter album also includes elements of jazz and swing-style drumming by Peart, which he had learned from Freddie Gruber during the interim between Counterparts and Test For Echo. In October 1996, in support of Test For Echo, the band embarked on a North American tour, the band's first without an opening act and dubbed "An Evening with Rush". The tour was broken up into two segments spanning October through December 1996 and May through July 1997. After the conclusion of the Test for Echo tour in 1997, the band entered a five-year hiatus primarily due to personal tragedies in Peart's life. Peart's daughter Selena died in a car accident in August 1997, followed by the death of his wife Jacqueline from cancer in June 1998. Peart took a hiatus to mourn and reflect, during which he travelled extensively throughout North America on his BMW motorcycle, covering 88,000 km (55,000 mi). At some point in his journey, Peart decided to return to the band. Peart's book Ghost Rider: Travels on the Healing Road is a chronicle of his journey. In the book, he writes of how he had told his bandmates at Selena's funeral, "consider me retired". On November 10, 1998, a three-disc live album entitled Different Stages was released, dedicated to the memory of Selena and Jacqueline. Mixed by producer Paul Northfield and engineered by Terry Brown, it features recorded performances from the band's Counterparts, Test For Echo, and A Farewell to Kings tours, marking the band's fourth live album. After a time of grief and recovery, and while visiting long-time Rush photographer Andrew MacNaughtan in Los Angeles, Peart was introduced to his future wife, photographer Carrie Nuttall. Peart married Nuttall on September 9, 2000. In early 2001 he announced to his bandmates he was ready to once again enter the studio and get back into the business of making music. CANNOTANSWER
