Andreas Oskar Hirsch works as a musician and visual artist. He has been inventing various musical instruments that he performs with, among others, the Electric Palm Leaf, as well as his latest construction, the Carbophon, a kind of a super-kalimba. Moreover, by connecting melodicas to the air chambers of a rubber boat or decoding bird calls via Morse code, he investigates sound, setups, narratives and performative processes and pushes them to a point where frenzy, humor, sense, and nonsense meet. Together with Patricia Koellges he runs makiphon, a label for experimental music and artist records based in Cologne, Germany.
