The celebration for Crosby, Stills & Nash‘s 40th anniversary hasn’t even begun yet and the legendary trio is already adding to the plans. CSN has added a second leg to its upcoming North American tour, which kicks off in early June. Following U.S. leg #1 and a trip to Europe, which includes an appearance at this year’s Glastonbury Festival, Crosby, Stills & Nash will return home for 12 more dates, highlighted by a headlining performance at both Gathering of the Vibes and Musikfest.

Tickets for the newly announced dates are currently available via Ticketmaster.com.

As previously reported, the tour will coincide with the release of a brand new compilation from Crosby, Stills & Nash on June 2nd. Aptly entitled Crosby, Stills & Nash Demos, the record will feature a mix of early demos and rarities, including a demo version of “Marrakesh Express”. The band is also reportedly at work on a brand new studio album with producer Rick Rubin.
