Rush is a Canadian rock band formed in August 1968, in the Willowdale neighbourhood of Toronto, Ontario. The band is composed of bassist, keyboardist, and lead vocalist Geddy Lee, guitarist and backing vocalist Alex Lifeson, and drummer, percussionist and lyricist Neil Peart. The band and its membership went through a number of re-configurations between 1968 and 1974, achieving their current form when Peart replaced original drummer John Rutsey in July 1974, two weeks before the group's first United States tour. Since the release of the band's self-titled debut album in March 1974, Rush has become known for its musicianship, complex compositions, and eclectic lyrical motifs drawing heavily on science fiction, fantasy, and philosophy. Rush's music style has changed over the years, beginning with blues-inspired heavy metal on their first album, then encompassing hard rock, progressive rock, and a period with heavy use of synthesizers. They have been cited as an influence by various musical artists, including Metallica, Primus, Rage Against the Machine and The Smashing Pumpkins, as well as progressive metal bands such as Dream Theater and Symphony X.
