 Itamar Assumpção was one of the biggest names and contributors in the "Vanguarda Paulista" ("São Paulo Vanguard" in English), an alternative scene that dominated São Paulo in the very late 70s and the first half of the 80s.This movement united artists who operated involuntarily outside of the established commercial music industry during an era that pre-dated the Internet, the politics of downloading and the contemporary indie music scene.The "Vanguarda" was responsible for launching many new talents and establishing a foundation for autonomous, self-sufficient music production (and subsequent release) by artists such as Arrigo Barnabé and Grupo Rumo.
