Author, director, performer and speaker Katharina Bihler, born in 1967, has been working with experimental theater, music, performance and radio plays since 1990. She conceives, realizes and writes in particular for projects that play with the boundaries of artistic genres and often deal with scientific, historical or European topics. A focus of Bihler's work is on the acoustic medium and the development of radio plays for radio. In 1997 she founded the Liquid Penguin Ensemble together with the composer and double bass player Stefan Scheib. She also works in other projects as a director or live actor.
The themes of Liquid Penguin Ensemble’s projects usually remain the subject of artistic research for a long time and sometimes find different artistic forms of expression over time. Sound installations are further developed into concerts or performances for small or larger ensembles, musical theatre pieces change into a purely acoustic form in radio plays for the radio, motifs and material from their radio plays form the basis for live performances. The most far-reaching project in this regard is "HEAR GRASS GROWING", which started in 2004 as a plant-controlled sound installation, which later resulted in various concerts and performances with plants in the following years, and then formed the starting point for a radio play of the same name (SR public radio, 2007), as a live radio play, that returned to the stage and most recently in 2019, at the invitation of the Modern Vienna Festival, became the basis of a production for young audiences and families as an "open day" at the biolingua Institute.
