With a multimedia lecture performance, Sigmund Freud's first practice on the mezzanine floor of Berggasse 19 is transformed into a soundscape spread over four rooms, those rooms with which David Josef Bach, one of the most important cultural promoters and cultural mediators in Social Democratic Red Vienna, was also well acquainted: as an early member of Freud's Psychological Wednesday Society, which gathered here almost every Wednesday evening in the years between 1902 and 1908.
