This song took inspiration from a fire in the Casino at Montreux, Switzerland
on December 4, 1971. The band was going to record their Machine Head
album there right after a Frank Zappa concert, but someone fired a flare gun at the ceiling during Zappa's show, which set the place on fire.
Deep Purple was in the audience for the show, and lead singer Ian Gillan recalls two flares being shot by someone sitting behind him which landed in the top corner of the building and quickly set it ablaze. Zappa stopped the show and helped ensure an orderly exit. Deep Purple watched the blaze from a nearby restaurant, and when the fire died down, a layer of smoke had covered Lake Geneva, which the casino overlooked. This image gave bass player Roger Glover the idea for a song title: "Smoke On The Water," and Gillan wrote the lyric about their saga recording the Machine Head
The band was relocated to the Grand Hotel in Montreux, where they recorded the album using the Rolling Stones mobile studio. They needed one more song, so they put together "Smoke On The Water" using Gillan's lyric and riff the guitarist Ritchie Blackmore came up with. The result was a song telling the story of these strange events just days after they happened - the recording sessions took place from December 6-21.
