Ernst Jansz represents an important part of Dutch pop history. In the 1960s he was part of the legendary hippie band CCC Inc. And later he made history by establishing the renowned band Doe Maar. Following his departure from Doe Maar he remained active. His father, born in Semarang on Java, is an Indo (Dutch-Indonesian), who went to the Netherlands in 1932 to continue his higher education after finishing his studies at the Batavia HBS. Much of the literary work of the author Jansz is based on his Indo identity and his fathers' heritage. His father became one of the few Indo advocates for an independent Indonesia.
