Nils Frahm releases a new double album, Old Friends New Friends, released by Leiter, the label he set up with his manager, Felix Grimm. The collection gathers together 23 solo piano tracks recorded between 2009 and 2021, almost all hitherto unreleased but, for one reason or another, omitted from previous albums and projects. Neither quite a new LP nor exactly a compilation, it offers “an anatomy of all my ways of thinking musically and playing,” Frahm says, adding with a smile, “Maybe I could say it’s an album I worked on for twelve years, and finally I have enough material?”
