Back in October, after a year of buildup, Matt Berninger of the National released his debut solo album, Serpentine Prison. As he told us in an interview last fall, Berninger initially approached producer Booker T. Jones about recording a covers album together, but the project eventually morphed into a collection of originals. They had accumulated enough covers, though, to release them in a separate capacity later on. As it turns out, that capacity is a new deluxe edition of Serpentine Prison out today.
