Rock & Roll Machine (also Rock 'N' Roll Machine) is the second studio album by Canadian hard rock band Triumph. It was first released in 1977 by Attic Records. The album contained in the band's first hit, a version of Joe Walsh's "Rocky Mountain Way".
A different "international" version of the album was released on RCA Records in the United States and other countries in 1978. This edition replaces some tracks from the original Canadian version with tracks from the self-titled debut Triumph (1976) album, along with new artwork.
The album was released for a second time in Canada, with a different cover than the original one or the international one, using the re-sequenced tracks from the international version. The international version was re-issued in the US on MCA Records in 1985.
The song The City: War March / El Duende Agonizante / Minstrel's Lament includes a rearrangement of Mars, the Bringer of War from Gustav Holst's The Planets.
