In his piece entitled "Trains", Bak creates a vast grey landscape with large mounts creating the structure of a train. Massive taper candles burn in the distance further down the train tracks, surrounding an eruption. The smoke from the candles and volcano pour into a sky of dark ominous clouds that lurk over the landscape. Here Bak has created a whole new meaning for "trains". Many of Bak’s pieces incorporate aspects of Jewish culture and the holocaust with a dark and creative twist, such as "Shema Yisrael, Alone," and "Ghetto""."
