On Friday (June 29th), Graham Nash will release a 30-track career retrospective, titled Over The Years. The set features tracks from Crosby, Stills, & Nash; Crosby, Stills, Nash & Young; Crosby & Nash; and Nash on his own. The new collection's second disc features a selection of Nash's personal demos of his best-known tracks taped between 1968 and 1980.

We asked Nash, what sets Over The Years apart from his 2009 critically acclaimed triple-disc collection, Reflections: "This is different because obviously a lot of people maybe have the 15 records of my fans' favorite Graham Nash songs -- I wanted to make it different, so I went back into my archive and I found 15 demos of my songs. Some from early-'69, all the way through to, y'know, 'Myself At Last' which was from a couple of years ago."
