Hiding at the bottom of Dave Holmes's (very entertaining) write-up of the March 23, 1988 pop charts is a link to an incredible document. It is titled "B-Rock Party." It is a home video, shot the night of June 28, 1988, of a party attended by some exquisitely 1988 suburban teenagers. At 1:36, a set of parents arrive home unexpectedly and, to the great benefit of future generations, the camera continues to record.
