Nouvelle vague, new-school early
60s French cinema:
Jean-Luc Godard,
Francois Truffaut, Alain Resnais, Eric Rohmer, etc.
The "new thing" in jazz in the 60s, both of the free jazz variety and the often-modal proto-free.
70s/80s pop music genre - punk rock sonically neutered and made safe to sell in mass quantities (at its money-grubbing worst); genuinely good pop classicism (at its best). See new-wave.
Authors for a kinder, less autocratic future.
