Six previously unheard recordings by late British singer/songwriter Nick Drake are expected to fetch at least $425,000 (£250,000) at auction.
Fellow folk star Beverley Martyn reveals the tapes are in "pristine" condition, despite being recorded 46 years ago. The tracks, including versions of Fruit Tree and Cello Song, were made months before the 1969 release of Drake's debut album Five Leaves Left.
She tells Independent.co.uk, "He was young, he sounds full of fun, he sounds light and his guitar playing is absolutely excellent. It really shows that he didn't need to have this whole layer cake of strings."
Martyn claims she decided to sell off the tapes due to her own failing health, adding, "Someone else should be able to enjoy it."
The memorabilia will go under the hammer at London auction house Ted Owen and Company on 31 July (14).
News of the auction emerges three months after Martyn shared another of Drake's unheard compositions, a duet between the pals, titled Restless Jane. It was included on her album The Turtle And The Phoenix.
Drake was just 26 when he committed suicide in 1974.
