Somehow Dominik has been in a music circuit since his forever. The band he’s part of is 52 Hertz Whale, and his solo project goes by the self-named Dominik Prok. He worked for a long time as a promoter in a DIY circuit and has now become quite institutionalised as a booker for the music venue Nová Cvernovka. He is also a part of the production team for festivals like the Pohoda Festival, Grape Festival and Sharpe, among others.
He will likely continue doing this for the rest of his life.
