Bast is credited with influencing the collective artist group Faile, with whom he has collaborated on numerous occasions. Such collaborations have been displayed on the streets as well as in joint exhibitions, namely Galerie Neurotitan Berlin in 2003, and New Image Art in Los Angeles in 2005. For the past ten years Brooklyn based artist Bast has been an intricate part of the street art movement. However Bast himself has remained an elusive character, rarely seen in public and whose very existence has often been debated. His paste ups spread across New York 's urban environment and are now common in the major European conurbations. In August 2007, Bast returned to New Image Art for a solo exhibition entitled ‘Those Bloody Yanks’ and also held a sell out show “Booby Trap’ at The Leonard Street Gallery in 2008.
