Alex Lifeson, Canadian singer-songwriter, guitarist, and producer
Aleksandar Živojinović, (born August 27, 1953), known professionally as Alex Lifeson, is a Canadian musician, songwriter, and record producer, best known as the guitarist and backing vocalist of the progressive rock band Rush. In 1968, Lifeson co-founded the band that would later become Rush, with drummer John Rutsey and bassist and lead vocalist Jeff Jones. Jones was replaced by Geddy Lee a month later, and Rutsey was replaced by Neil Peart in 1974.

With Rush, Lifeson played electric and acoustic guitars, as well as other string instruments such as mandola, mandolin, and bouzouki. He also performed backing vocals in live performances as well as the studio albums Rush (1974), Presto (1989) and Roll the Bones (1991) and occasionally played keyboards and bass pedal synthesizers. Like the other members of Rush, Lifeson performed real-time on-stage triggering of sampled instruments. Along with his bandmates Geddy Lee and Neil Peart, Lifeson was made an Officer of the Order of Canada on 9 May 1996. The trio was the first rock band to be so honoured as a group. In 2013, he was inducted with Rush into the Rock & Roll Hall of Fame. Lifeson was ranked 98th on Rolling Stone's list of the 100 greatest guitarists of all time and third (after Eddie Van Halen and Brian May) in a Guitar World readers' poll listing the 100 greatest guitarists.The bulk of Lifeson's work in music has been with Rush, although Lifeson has contributed to a body of work outside the band as well. Aside from music, Lifeson has been a painter, a licensed aircraft pilot, an actor, and the part-owner of a Toronto bar and restaurant called The Orbit Room.
