This month marks the 35th anniversary of Rush’s landmark album Moving Pictures, and to celebrate the occasion, the Rock and Roll Hall of Fame-inducted prog rockers have unveiled a “megamix” for the LP’s most popular track “Tom Sawyer.” The live video seamlessly weaves together footage of Rush playing “Tom Sawyer” over the past 13 years using performances of the set list staple culled strictly from the band’s steady stream of concert films.
