A set of 149 acetate recordings by Bob Dylan has come to light after being discovered in a Greenwich Village apartment earlier this year.
Dylan had used the building as a studio during the early 1970s, while living just a few blocks away on McDougal Street.
The executor for a woman who lived in the tenement discovered them while cleaning out her home and got in touch with a collector named Jeff Gold.
Gold wrote on the music memorabilia site Recordmecca: "When I opened the boxes and took a quick look at the contents, I was blown away. They were indeed all by Dylan, all were in excellent condition, and many had handwritten notes on the sleeves.
"The sound on a carefully preserved acetate can be incredible - it's a first generation record made in real time directly from the master tape. And that was the case here."
The records were created during sessions for the seminal albums Nashville Skyline, Self Portrait and New Morning and include a wealth of unreleased versions of songs, new edits and outtakes.
Gold will offer some of the records for sale through the site.
In June, Dylan's original lyrics to Like a Rolling Stone sold for $2m at Sotheby's New York - a new world record for a pop music manuscript.
