ContendisA new computer application dedicated to Crosby, Stills & Nash is now available for purchase via the Apple App Store.  The Official Crosby, Stills & Nash App is a subscription-based program that costs $3.99 a month or $39.99 a year, and offers an in-depth look at the famed folk-rock trio, as well as an overview of the band members' various other musical endeavors, such as The Byrds, Buffalo Springfield and The Hollies.

The app features four special areas -- titled "The Attic," "The Studio," "The Road" and "The Living Room" -- that respectively focus on CSN's history, their recordings, their tours, and personal information and updates about David Crosby, Stephen Stills and Graham Nash.  Subscribers also will be treated to exclusive content and rare or unreleased tracks.  New features will be added continuously to the app.

In addition, the app allows users to link directly to Crosby, Stills & Nash's official websites, social media sites and online store.

"Use this app as an open door to our music," says Nash.  "And, as usual, when one door closes -- another one opens...enjoy exploring."
