Experience Hendrix, a Seattle-based company that controls rights to rock guitarist Jimi Hendrix’s music and likeness, is adamant that Vivid Entertainment’s “sexual documentary” Jimi Hendrix: The Sex Tape is not authentic.

“We strongly dispute the claimed authenticity of the tape,” the entertainment firm said in a statement released on Thursday. “We view the release as nothing more than a callous attempt to trade on the image and reputation of a deceased artist who is unable to defend himself against such an outrageous and baseless assertion.”

On Tuesday, Los Angeles-based adult video company Vivid Entertainment released a forty-five minute sex tape produced in the 1960s, which it purports features Hendrix getting it in with a couple of brunettes.

Jimi Hendrix, who is widely considered one of the most prolific guitarist in the history of music, died in 1970. He was twenty-seven years old.
