Valium Aggelein was a side project of Californian lo-fi slowcore band Duster. The alias' debut album Dweller On The Threshold was released on cassette in 1997 by the now-defunct label Astronavigation. It came packaged inside a plastic bag with a stenciled box, handwritten note and decorative syringe. Their second album, Hier Kommt Der Schwartze Mond, was released in 1998 on vinyl via AudioInformationPhenomena. The alias became inactive as a result of Duster's extended hiatus in 2001
