The Flare Gun That Burned Down Montreux Casino and Created “Smoke on the Water”

In December 1971, British hard rock pioneers Deep Purple arrived in Montreux, a tranquil resort town on the edge of Lake Geneva in Switzerland. They had rented the Rolling Stones Mobile Studio, a pioneering 16-track facility housed inside an anonymous lorry, and parked it outside the Montreux Casino entertainment complex. Their plan was straightforward: set up inside the venue’s cavernous theatre hall to record a dynamic live-sounding studio album, free from conventional studio curfews.

 

Before Deep Purple could unload their gear, one final concert had to take place in the arena: Frank Zappa and the Mothers of Invention.

 

An Afternoon Turned to Ash

On 4 December 1971, during Don Preston’s synthesiser solo, someone in the audience fired an emergency flare gun straight into the venue’s wooden rattan ceiling. The dry wicker insulation caught fire immediately. Frank Zappa calmly directed the audience toward the exits, urging everyone not to panic while stage hands and local promoter Claude Nobs rushed into action.

 

Nobs, who had founded the Montreux Jazz Festival, personally ran back into the burning building multiple times to usher out trapped concertgoers. Despite the speed with which the wooden hall became an inferno, no lives were lost. The casino itself, along with Zappa’s live equipment, was reduced to a skeleton of scorched iron and concrete.

 

The Mobile Studio on the Move

Deep Purple watched the blaze from the terrace of their hotel across the bay. As the building burned down to the water’s edge, thick columns of black smoke rolled across the alpine lake. Days later, bassist Roger Glover woke from a dream with a simple four-word phrase in his head: Smoke on the Water.

 

Displaced and racing against tight deadlines, the band attempted to track songs at a nearby venue called the Pavillon. Local residents swiftly complained about the deafening volume, leading police to intervene while the band finished laying down a raw, syncopated four-note riff written by Ritchie Blackmore.

 

The local authorities shut them down, forcing a final move to the empty Grand Hôtel. There, in freezing corridors padded with mattresses and red lighting, Deep Purple captured the rest of Machine Head, turning a real-world disaster into one of the most recognisable anthems in rock history.
