Fleetwood Mac star Stevie Nicks has revisited her past for a new album of rarities, which will be produced by rocker Dave Stewart.

The singer took to YouTube.com to watch clips from past concerts and uncover lost treasures that were never formally released.

The result is the album 24 Karat Gold: Songs From The Vault, which consists of new versions of obscure tracks she found online.

She explains, "We went onto YouTube and we found all the songs that, somehow, were taken from my house or picked up or loaned out or whatever, and we went to Nashville (and recorded them). They're, like, all starting from like 1969. I call them my 24 karat gold songs."
