As an afterthought...
There's a great scene in the first season of Mad Men where Don Draper gets into the apartment of his artist-lover. Frustratingly, the artist-lover is not alone. She is there with her beatnik friends who all get together in order to listen to the latest album by Miles Davis. In 1960, it was Sketches of Spain. Now the scene makes many good points (not forgetting the final grand gesture from Don; dirty money to a dirty artist), but to me it has always been about that new LP and how people got together to listen to it in a dimly lit apartment of New York City. Behind the curtains and over several hours of doing nothing but smoking weed.
A whole album. Imagine that.
