In December 1971, Deep Purple travelled to Montreux, Switzerland, with a clear plan: they wanted to record their new album at the shores of Lake Geneva.
For the recording, they had rented the Rolling Stones Mobile Studio – a fully equipped recording studio inside a truck that could be parked wherever the band needed it.
But then, on December 4, everything changed.
That evening, Frank Zappa & The Mothers of Invention were performing at the Montreux Casino. During the concert, a member of the audience fired a flare gun towards the ceiling.
The ceiling caught fire.
Within minutes, the casino was engulfed in flames. The building burned while a huge cloud of smoke slowly spread across Lake Geneva.
The members of Deep Purple were watching from the other side of the lake.
And that image – the smoke rising over the water – would eventually become one of the most famous phrases in rock history:
“Smoke on the water.”
But the story didn't end with the fire.
The casino was destroyed, which meant that Deep Purple suddenly had nowhere to record their album. They had to find another location.
Eventually, they ended up at the empty Grand Hotel in Montreux.
There, they improvised a recording studio. Rooms became recording spaces, corridors were used to run cables, and the unusual surroundings became part of the atmosphere of the recordings.
It was under these extraordinary circumstances that Machine Head began to take shape.
And somewhere in that chaotic period, one of rock music's most recognizable guitar riffs was born.
The strange thing about the whole story is that one of the most famous rock songs ever written was inspired by something that had nothing to do with the music itself:
a casino fire.
And the fire itself wasn't part of the show.
It was an accident.
Sometimes, rock history simply writes its own songs.
