Deep Purple released Machine Head in 1972. The album reached number one in the UK, but it didn’t do as well in the US. It was re-issued several times.

Machine Head also helped establish traditional metal. The album features seven slabs of hard rock. The album was recorded in Montreux, Switzerland, in December 1971. The first single was “Highway Star.” This is a simple rocker, showcasing the band’s ability to write traditional ballads. The second single was inspired by a fire at the Montreux Casino.
