Stephen Stills on Instagram: "Preview two songs from CSNY’s upcoming album, ‘Live At Fillmore East 1969’ - a stunning rendition of David Crosby’s “Long Time Gone” and Graham Nash’s impromptu performance of “Our House” which he had just written about himself and Joni Mitchell, who was in the audience that night. Available on 2xLP and CD formats, out everywhere on October 25th. Pre-order available now, links in bio."
