Don’t know much about this video, other than it was filmed early in 1974, not long after Rush released their first self-titled album. Rush was released on March 1, 1974 by the band’s own label Moon Records in Canada and by Mercury Records in the United States and internationally. According to interviews over the years, the members of Rush were fans of such bands as Led Zeppelin and Cream, and those influences can be heard in most of the songs on this first album.
Original drummer John Rutsey performed all drum parts on Rush, but was unable to go on extended tours because of his diabetes and simply retired from the band after the album was released. Rutsey was eventually replaced by Neil Peart, who has remained not only Rush’s drummer but also their primary lyricist.
According to the YouTube description:
A rare Rush clip featuring the late John Rutsey on drums. Filmed in the spring of 1974. Rutsey was forced to leave the group later that year due to health reasons. His replacement was Neil Peart.
