Deep Purple witnessed the fire at Montreux Casino in Switzerland on December 4, 1971, an event that became the subject of “Smoke on the Water.” Frank Zappa and the Mothers of Invention were performing when a flare fired into the ceiling set the building alight. Purple had planned to record Machine Head there. Before the sessions could begin, their chosen venue was gone.
The casino was part of a deliberate recording decision. Purple wanted to work outside a conventional studio, using the Rolling Stones’ mobile recording unit to capture them playing in the concert space. Bassist Roger Glover explained in a 2024 interview with ClassicRockHistory.com that the casino’s loud, lively atmosphere appealed to them, and they had arranged three weeks with the mobile. Losing the building meant finding another room where they could make that approach work within the time available.
Montreux Jazz Festival organiser Claude Nobs helped keep the sessions in town. The casino had hosted his festival as well as concerts throughout the year; its destruction left him searching for somewhere Purple could record. He found the Pavillon des Sports, but the replacement brought its own problem. It wasn’t soundproofed, and the band’s late-night playing carried into the surrounding neighbourhood. That was where “Smoke on the Water” began taking shape as a recording. Glover told SWR1 in 2017 that, after a day spent setting up and checking microphones, the musicians returned from dinner and Ritchie Blackmore started playing the riff. The others joined in, finding spaces for verses and solos as they played. Police were trying to halt the session because the noise was keeping the town awake. The band got a take, then had to find another base.
Nobs secured the Grand Hotel in Territet, which was closed for the winter. Mattresses helped make its interior usable for recording, with the mobile studio parked outside. In recollections published by Classic Rock in 2023, singer Ian Gillan described equipment spread through the building to separate the instruments without making everyone turn down. Getting out to the truck to hear a playback was awkward and cold, so they tended to keep working until a performance felt ready to check.
The fire also supplied the words. Glover recalled waking with “Smoke on the Water” in his head and taking the title to Gillan over breakfast. The lyrics followed their own experience: arriving in Montreux, losing the casino, searching for another location and eventually recording at the hotel. Nobs entered the song as “Funky Claude.”
The song was also a practical solution to a gap in the album. As Glover explained in the 2024 interview, the band returned to the Pavillon recording because they were one track short. “It was a very natural thing that came out of habit,” he said. They finished the record without knowing which song listeners would seize on.
“Smoke on the Water” appeared on Machine Head in March 1972. Its U.S. single release followed in May 1973, and it reached No. 4 on the Billboard Hot 100.
