On May 20, the Highwaymen will be forever immortalized in The Highwaymen Live: American Outlaws, a deluxe DVD / CD box set featuring the legendary work of Willie Nelson, Johnny Cash, Waylon Jennings and Kris Kristofferson, who joined together to form country’s first-ever supergroup.

The Highwaymen Live: American Outlaws will include two discs of a performance at Nassau Coliseum in Uniondale, N.Y., recorded in 1990, along with a never-before-released concert film of the show. The set also includes a disc of tracks recorded at Farm Aid festivals throughout the years and debuts a cover of Bob Dylan’s “Too Many Mornings,” recorded by Nelson and Kristofferson in 2014.

Although Cash and Jennings have since passed away, the Highwaymen are still remembered and lauded. During the recent The Life & Songs of Kris Kristofferson tribute concert at Nashville’s Bridgestone Arena, Jamey Johnson and Jennings’ son Shooter Jennings joined Kristofferson and Nelson onstage to play “Highwayman,” the quartet’s debut single that won Best Country Song at the 1986 Grammy Awards.

One week after The Highwaymen Live's release, on May 27, PBS will air a feature-length documentary about the Highwaymen. A broadcast edit of The Highwaymen: Live at Nassau Coliseum (featured in the box set) is set to air in June.
