Day is Done boasts a smartly selected range of original and borrowed material, from Tin Pan Alley jazz standard "No Moon At All," made famous by Nat King Cole, to "Knives Out" from Radiohead's Amnesiac. Day is Done also includes two of Mehldau's own pieces, "Artis" and "Turtle Town," plus a cover of contemporary tenor sax player Chris Cheek's "Granada," which Mehldau originally performed on Cheek's vine.
