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 iconic lineup when Peart replaced original drummer John Rutsey in July 1974, two weeks before the group's first United States tour. Rutsey's departure stemmed primarily from health concerns regarding his diabetes. In 2015 the band played their final show due to Peart's declining health.
