Day Then Night (1977)

It's midday in sleepy San Diego. Everything is moving sluggishly in the hot sun. Kind of spooky. But night falls quickly and multiple drum rolls signal the onset of the night, the hectic breakneck buzz of crass neon and porno marquees, cars hurtling through the "bad" part of town, hyped up nightlife glitz. An impressionistic portrait of urban glitter and grit that moves to a rock beat.
