Eleven! "Time zones" is one of thé utterly superior slices of cut ‘n’ paste radio taping montage ever. It's off the “Escape From Noise” lp (SST 1987) by Negativland, thé masters at the media reappropriation craft. Ten years later, after the break i.e., their “Truth in advertising” single (Eerie Materials, 1997) would set another standard.
