 In 2008 "Reine Vernunft" (Pure Reason) was presented at the Hamburger Bahnhof in Berlin.It was their first comprehensive appearance in the capital.According to the museum, the works provide "an overview of the ironical and philosophical strategy of this artistic team" and show "intensive dedication to a continuous process of self-experimentation", with the Blumes having "performed groundwork on the nature of German existence" by investigating "'home sweet home' for every conceivable form of misery" rather than entering the wider world.
