Machine Head is the sixth studio album released by the English rock band Deep Purple, recorded in December 1971 at Montreux, Switzerland and released on 25 March 1972 on Purple Records. Following intermittent recording sessions between gigs for earlier albums, Deep Purple wanted a dedicated amount of time to record an album away from the typical studio environment that sounded closer to their live shows.They hired the Rolling Stones Mobile Studio for recording, and block booked the Montreux Casino as a venue, but during a Frank Zappa concert immediately before the sessions, it burned to the ground. The band managed to book the Grand Hotel, closed for the winter, and converted the hotel into a live room suitable for recording.Track Listing:1. Highway Star2. Maybe I\'m a Leo3. Pictures of Home4.
