KISW-FM 99.9, seattle- progressive rock station that veered amazingly far into frothy pop. this was back in the glory days of album-oriented rock and they would play the whole album. it was where i first heard the rick wakeman album, "rhapsodies" [very late-70s cheesy synths].
KING-FM 98.1, seattle- back in the 70s a "progressive" classical and jazz station, at night they’d play jazz. it is where i was first exposed to Canadian bandleader rob mcconnell.
KLAY-FM 106.1, tacoma- a progressive/new-wave station where i first heard those kinds of tunes, where i first heard punk, late 70s.
KNBR-680AM- san francisco, late 70s then a progressive news station, where i first heard left-wing politics. i heard this station via atmospheric "skip" for the first time.
KSL-AM 1160, back in the 70s the originator of a late night call-in talk show called "Nightcaps" hosted by herb jepko. very laid-back informal format, adult in a very calm way. reasoned discourse. i miss it.
