Johann Theo (or just Theo) produces music and games under the alias treehann. He has been immersed in music—particularly electronic music—since early childhood, and has published compositions on the web since 2009. Beginning in chiptune, his style has moved in more modern directions, influenced by producer-DJs (Ivy Lab, Lone, Submerse), pioneers (Aphex Twin, Kraftwerk), game composers (Disasterpeace, Nifflas, 4mat, Nobuo Uematsu), and a variety of math rock, jazz, and metal acts (Yvette Young, BadBadNotGood, SikTh). Composing background music for successful games published by other developers and being active in the network of experimental electronic music producers, Theo has established a dual-foothold in game audio and music for dedicated listening. He is keen to further collaborate with artists of all varieties.
