Musicians die, music lives for ever, goes the received wisdom. Rock history is replete with artists who did not live to get old but refuse to fade away: Jimi Hendrix, Kurt Cobain and Eva Cassidy to name but a few.
Charlie Haddon, lead singer of the north London band Ou Est Le Swimming Pool, was an unlikely candidate to join what Cobain's mother called "that stupid club" of stars who are – to put it crudely – worth more dead than alive. But in August, Haddon fell to his death from a telephone mast after a gig in Belgium, aged just 22.
Thanks to the coverage of the tragedy, the release of their album today will almost certainly get the type of attention and sales that previously the group could only have dreamed of.
The chances are that if Haddon had not died as he did few of us would know, or care, anything about Ou Est Le Swimming Pool, a synth pop band in the guitar age. But the same is true of Cassidy, Nick Drake and, to a degree, Jeff Buckley.
Formed in 2008, the band had yet to release an album and was supporting better-known artists such as La Roux and Example. Today, however, record shops are bringing in extra stock to prepare for an anticipated increase in demand for the album, The Golden Year.
While this may appear callous, on past experience it is simply prudent, as the relationship between death and music is undeniable.
Michael Jackson's music made more money ($1bn) in the 12 months after his death last year than during his whole 40-year career. On a less stratospheric level, sales of Nirvana's last album, In Utero, more than doubled in the week after lead singer Kurt Cobain killed himself.
Before Cassidy's death in 1996 she was little known outside of Washington DC, but her posthumous albums have sold more than eight million copies. And when the rapper The Notorious B.I.G was killed, aged 24, in a drive-by shooting, his album Life After Death was released just 15 days later and went straight to No 1 in the US.
Gennaro Castaldo, an HMV spokesman, confirmed its stores had increased orders of The Golden Year. "We do get this emotional response when people die, and people will go and buy a CD."
A spokeswoman for Ou Est Le Swimming Pool said that it had been a tough decision to release the album. "Of course there's more coverage because of what happened, so inevitably it will be more high profile than it would have been. The band sat down with Charlie's family, who all agreed that's what Charlie would have wanted."
Jamie Fullerton, the news editor of music magazine NME said: "They say life brings out the best in people and death the worst. But any posthumous commercial spike from an artist is usually down to cynical marketing rather than mortality – as the multi-million-pound record deals signed pretty much while Michael Jackson's cheeks were still warm demonstrate."
It remains to be seen whether Haddon's place in musical history will echo those of Notorious and Cassidy or will be summed up in a Wikipedia footnote. But his contemporaries will gather to remember him at a charity concert, called Chazzstock, at Koko in Camden, north London, tomorrow. The gig, in aid of the mental health charity Mind, will feature artists such as the Kooks, and former Spandau Ballet singer Tony Hadley.
