Alex Lifeson is a Canadian musician, known as the guitarist for the rock group Rush. Lifeson founded Rush in the summer of 1968, and has been an integral member of the three-piece band ever since. For Rush, Lifeson plays electric and acoustic guitars as well as other stringed instruments such as mandola, mandolin and bouzouki. He also performs backing vocals in live performances, and occasionally plays keyboards and bass pedal synthesizers. During live performances, Lifeson, like the other members of Rush, performs real-time triggering of sampled instruments, concurrently with his guitar playing. The bulk of Lifeson's work in music has been with Rush, although Lifeson has contributed to a body of work outside of the band as well.
