Title:
Paris

Context:
Immediately after the War The Saint-Germain-des-Pres quarter and the nearby Saint-Michel quarter became home to many small jazz clubs, mostly found in cellars because of a lack of space; these included the Caveau des Lorientais, the Club Saint-Germain, the Rose Rouge, the Vieux-Colombier, and the most famous, Le Tabou. They introduced Parisians to the music of Claude Luter, Boris Vian, Sydney Bechet Mezz Mezzrow, and Henri Salvador. Most of the clubs closed by the early 1960s, as musical tastes shifted toward rock and roll. 

Question:
When did most of the jazz clubs close down?

1960s
