When it comes to wistful indietronica, the Morr Music gang has pretty much got the game on lock. Vienna’s B. Fleischmann has been making these kinds of records for nearly a decade, so he’s mastered all the tricks–the melancholy piano lines, ambient background fuzz, gently plucked guitars, and skittery bedroom beats are all here. What sets Angst apart is Fleischmann’s use of guest vocalists, especially Sweet William Van Ghost (“Hello,” “24:12,” “In Trains”), whose dusky tones sound like a cross between Casiotone for the Painfully Alone and The National’s Matt Berninger. Even Daniel Johnston makes an appearance, lending his oddball pop credentials to “Phones, Machines and King Kong.”
