Analog radio is almost an anachronism, KZSU is an anachronism - vinyl is alive and well, punk rock is not dead. But it persists because it is populated by people who love, who are obsessed with, music. The DJs who stay - and some stay for more than 20 years - are the ones who would consider being described as "normal" an insult. They are aging hippies, computer nerds, paranoids, slackers, artists, homeless drifters, musicians who build their own instruments, and music snobs for whom mainstream music is not only tasteless but immoral. They come to the Zoo to exercise their creativity, to sate their music lust.
