In an article on Billboard.com, Graham Nash offers some insight into the forthcoming Crosby, Stills & Nash album. Nash indicates that the project, which is being produced by Rick Rubin, is about a third of the way complete. It will focus on cover material with songs now in the mix such as: the Grateful Dead’s “Uncle John’s Band,” the Allman Brothers Band’s “Midnight Rider,” Bob Dylan’s “Girl From the North Country,” the Beatles’ “Norwegian Wood,” and Rolling Stones’ “Ruby Tuesday.” The trio has already added several of the covers to its live set.

CSN is currently on tour and will be at the Louisville Palace Theatre in Louisville, KY on Saturday.
