The National have been planning a Grateful Dead tribute album for quite some time, and when we profiled the band last year they elaborated a bit on its progress. By December we confirmed tracks from Justin Vernon with Bruce Hornsby, the War On Drugs, the Walkmen, Marijuana Deathsquads, Unknown Mortal Orchestra, Grizzly Bear’s Daniel Rossen, and Phosphorescent among others.

This week Jam Base highlighted a series of tweets that detailed another round of contributions. The collection is supposedly five hours and 28 minutes long and includes: Courtney Barnett (“New Speedway Boogie”), Wilco with Bob Weir (performing “St Stephen” live), Tunde Adebimpe with Lee Ranaldo (“Playing In The Band”), Stephen Malkmus And The Jicks (“China Cat Sunflower/I Know You Rider”), Vijay Iyer (“King Solomon’s Marbles”), Lucius (“Uncle John’s Band”), Orchestra Baobab (“Franklin’s Tower”), Kurt Vile with J Mascis (“Box Of Rain”), Ira Kaplan + Friends (“Wharf Rat”), Perfume Genius with Sharon Van Etten (“To Lay Me Down”), Angel Olsen (“Attics Of My Life”), Fucked Up (“Cream Puff War”), Flaming Lips (“Dark Star”), Tal National (“Eyes Of The World”), The National (“Morning Dew”), Jim James & Friends (“Candyman”), and Antony (“Black Peter”).

The tribute album’s live debut will take place at this year’s Eaux Claires Music & Arts Festival.
