After this Graham broadened his conceptual practice development with performance, film, video and sculpture including "Rock My Religion" (1984) and "Performer/Audience/Mirror" (1975). His installations such as "Public Space/Two Audiences" (1976) or "Yesterday/Today" (1975) further inspired his move to the indoor and outdoor pavilions he most recently designs. His many conceptual pavilions including "Two Way Mirror with Hedge Labyrinth" (1989) and "Two Way Mirror and Open Wood Screen Triangular Pavilion" (1990) have increased his popularity as an artist. Dan Graham's first sculpture building project was "Café Bravo" at Kunst-Werke Institute for Contemporary Art in Berlin. After a lecture at the Berlin University of the Arts, Klaus Biesenbach invited Dan Graham to conceive the pavilion for Kunst-Werke, which Biesenbach founded, and he assisted Graham in the realization of the project.
