David Crosby, Stephen Stills and Graham Nash — known collectively as Crosby, Stills & Nash (CSN) — have expanded their summer touring plans for the U.S. through the end of summer. The folk-rock trio’s second leg of national concerts picks up July 26 at the Gathering of the Vibes Festival in Bridgeport, CT, and stretches through September 28-29 at Humphrey’s Concerts by the Bay in San Diego, CA.

With the addition of more than 10 shows, the entire U.S. tour is now scheduled to hit 23 cities throughout the summer months. Highlights of the most recently added dates are an August 1 performance at Pabst Theater in Milwaukee, WI, and an August 14 concert at Filene Center at Wolf Trap in Vienna, VA.

The new round of shows follows the supergroup’s previously announced June tour, which is scheduled to visit nine cities in the Northeast. The opening run includes the tour’s only Canadian date at this point, a June 9 performance at Fallsview Casino in Niagara, ON.

General information about ticketing pricing and on-sale dates for the entire trek can be found on the official CSN Web site.

CSN’s tour coincides with the June 2 release of “Crosby, Stills, & Nash Demos.” The compilation features early demos recorded during the trio’s studio sessions from 1968 through 1971. The musicians released their debut collaboration in 1969, gaining popularity during their brief years together with their complex harmonies and Top 40 hits “Marrakesh Express” and the widely popular anthem “Teach Your Children.”
