Rock becomes all things. Rock changed almost by the day, evolved and experimented, and, most of all, in its infinite variety of moods and emotions and ideas, it reflected all the rest of the 1960s' puzzling exuberant, gaudy life. Rock has of course always communicated with the young. In the beginning, when rock'n'roll consisted of little more than raw vitality, only the kids received its message. In the 60s, when rock does have a meaning for North America's over-thirties, it is still youth's special preserve.
Kids move to rock.
It's probably the most important thing in their lives - more important, anyway, then moon shots or philosophy or parliament. But there are other questions. Frank Zappa, leader of the Mothers of Invention and the shrewdest man in rock, thinks the music is pure commerce. And certainly rock is a thoroughly capitalistic enterprise. The audiences tend to have the same moneyed look.
