Everyone in The National is a total Deadhead, which helps to explain how those guys could play “Sorrow” for six straight hours at MoMA. They band has talked before about bridging the gap between fans of the legendary jam band and the indie-rock set with a charity compilation, and that idea has now evolved into an actual project. In a new interview with Radio.com, Bryce Dessner and Matt Berninger discussed the status of its Grateful Dead tribute album, noting that Bon Iver, Vampire Weekend, Kurt Vile, and The War On Drugs have all agreed to contribute tracks. Dessner also mentioned getting calls from Fucked Up and Lee Ranaldo of Sonic Youth. There’s no official release date yet, but it’s expected to be out sometime in 2014.
