HANS BILGER is a Berlin-based musician, recording engineer, and bioacoustician.

As a recording engineer and producer, Bilger has worked across a wide range of genres and contexts — from symphony orchestras to indie bands, traditional Romanian song to electroacoustic flute pieces. He has worked on production teams for recordings on ECM Records and his engineering work has been featured on Apple Music's Best New Songs. His studio, Two Fields Sound, is based in Berlin's historic Funkhaus. He has also taught courses on recording and artist development at Bard College Berlin and Universität der Künste.

Bilger also has a deep background in the science of sound. He holds a doctorate in evolutionary bioacoustics from the University of Texas at Austin and has published research on the musicality of birdsong and the evolution of the voice in frogs, bats, and humans in journals such as Frontiers in Psychology and Bioacoustics. Currently, these interests are feeding a new project: We Beasties, a children's literature and music show exploring the perceptual worlds of different animals.
