Duster is a San Jose, California based post-/space-rock band from the late 90's. They reformed two years ago and reissue their gradually by their new label and they did the same with their side project Valium Aggelein. As far as I know they only released one album Hier Kommt Der Schwarze Mond/The Black Moon. And Valium is their agenda. I rather call it spacey slow core because rhythm is reduced to a minimum and only guitar improvisations rule their songs added with slight drums and piano fragments. Not a sound from earth.
