Performers Memina and Laura Gambarini use their lower backs to create characters during their performance at the Butt and Better alternative fashion and arts festival in Berlin, January 21, 2012. Butt and Better is a festival of underground fashion and performance art conceived as a non-commercial alternative to the Bread and Butter fashion fair that is endorsed by Berlin’s Mayor Klaus Wowereit. During four nights designers, artists and performers turn a derelict former east Berlin factory building into a venue where they celebrate the free-wheeling creative spirit of post-unification Berlin that organisers say is lost in today’s increasingly gentrified capital.
