David Crosby, Stephen Stills, and Graham Nash, who have been playing together for over 40 years, are back on the road again, promoting nothing but their extensive catalog and undying passion for music. And that passion must be strong for these guys to STILL be touring after all this time. It's no secret that the members of this band aren't the best of friends off stage all the time, but what relationship doesn't have problems after such a long period of time in close proximity? Plus, their musical influence is popping back up again in semi-mainstream music (The last Fleet Foxes album is undoubtedly a direct descendant) and political activism is as vogue as ever. Why stop now? Tickets aren't yet on sale, so stay tuned to Crossfade for more information on their upcoming Hard Rock Live show.
