Photo above - famously, Hendrix carved out those incredible sounds left handed - here's the proof.
The astonished audience looked on as the renegade guitarist was rushed off by petrified venue staff and taken to hospital with minor hand injuries.
As the fuss died down his guitar was retrieved by roadies and eventually returned to Garland's London offices. The frazzled guitar was then kept at the home of Noel Redding (bass player with the Jimi Hendrix Experience) before Garland collected the guitar and stored it at his parent's garage in Hove - and only unearthed by Garland's nephew in 2007.
Of course, Hendrix repeated the stunt at the Monterey Pop Festival in 1967, but the Astoria guitar remains the only surviving burnt guitar fully intact - with burns still visible along the neck and scratch plate.
Idea Generation Managing Director Hector Proud said: "The sale of Hendrix's guitar marks such a fascinating time in his story, when he was on the cusp of major success and recognition in the UK."
"When he burnt his guitar at the Astoria, it signified a new era in self-promotion, in what was effectively one of the first - and most successful - publicity stunts by a musician."
"Idea Generation Gallery will provide a fitting auction venue, as the sale follows our retrospective of Robert Altman - the chief staff photographer for Rolling Stone magazine in the 1960s - and someone whose work
vividly documents the period in which Hendrix was such an important figure."
