The guitar that Bob Dylan plugged in when he famously went electric at the 1965 Newport Folk Festival sold at auction Friday for a record $965,000 US — the highest price ever paid for a guitar at auction.

Christie's auction house did not immediately identify the absentee buyer of the sunburst Fender Stratocaster.

Dylan's legendary performance at the festival in Rhode Island 48 years ago marked his rupture with the folk movement's old guard and solidified his shift away from acoustic music, like Blowin' in the Wind, to electric rock 'n' roll, such as Like a Rolling Stone.

The raucous, three-song electric set was booed by some in the crowd, and folk purists saw Dylan as a traitor and a sellout.

But Dylan's "going electric changed the structure of folk music," said Newport Folk Festival founder George Wein, 88.

"The minute Dylan went electric, all these young people said, 'Bobby's going electric. We're going electric, too."'

The pre-sale estimate by Christie's for the guitar, which was sold with its original black leather strap and Fender hard shell case, was $300,000 to $500,000 US. The previous record for a guitar sold at auction was held by Eric Clapton's Fender, nicknamed "Blackie," which sold at Christie's for $959,500 US in 2004.

Held by N.J. family for decades

With a classic sunburst finish and original flat-wound strings, Dylan's guitar had been in the possession of a New Jersey family for nearly 50 years. Dylan left it on a private plane.

The pilot's daughter, Dawn Peterson of Morris County, N.J., said that her father asked Dylan's management company what to do with the guitar but nobody ever got back to him.

Last year, she took it to the PBS show History Detectives to have it authenticated, and experts matched the wood grain on the instrument to close-up color photos of the guitar taken at the 1965 festival.

Dylan's attorney and his publicist didn't respond to email and phone requests for comment. Dylan and Peterson, who declined to be interviewed, recently settled a legal dispute over the items. The terms weren't disclosed.

Historic performance

Dylan's Newport performance — like Elvis Presley's above-the-hips appearance on The Ed Sullivan Show, or the Beatles' arrival in America, or Woodstock — is regarded as one of the milestone moments in rock history.

By going electric, Dylan helped lead a movement that gave rock 'n' roll lyrics the density and ambiguity of literature.

Exactly what happened at the festival on July 25, 1965, has become enshrouded in legend, and to this day, the debate persists over whether those who booed were angry over Dylan's electric turn or were upset over the sound quality or the brief set.

Backed by a band that included Mike Bloomfield on guitar and Al Kooper on organ, Dylan played such songs as "Maggie's Farm and Like a Rolling Stone. He returned for an acoustic encore with It's All Over Now, Baby Blue.

Legend has it that Pete Seeger, one of the elder statesmen of the folk movement, was so angry that he tried to pull the plug on the electric performance or threatened to cut the cable with an axe. But years later, Seeger said he had nothing against Dylan going electric — he was upset over the distortion-filled sound system.

Christie's also was offering five lots of hand- and typewritten lyric fragments found inside the guitar case — early versions of some of Dylan's songs. They had a presale estimate ranging from $3,000 to $30,000 US. But only one of them sold; it went for $20,000 US and contained draft lyrics for I Wanna Be Your Lover.
