In 1967-68 when I was in high school, KPRI started broadcasting "underground radio" during the overnight hours. I used to set my reel-to-reel recorder to tape it so I could listen to it the next day (man do I wish I had those tapes!), and sometimes I used those small speakers designed to go under the pillow to sneak in a listen when I was supposed to be getting rested up for school the next day.
The original program director of the underground format as I recall (and this is all real fuzzy) was a guy name Steve Brown, who went by the air name of OB Jetty, because he lived near the jetty in Ocean Beach. He was either in the Navy then or had just gotten out. It wasn't too long before the whole station went underground. Gabriel Wisdom worked there (I think he was Okmod the Revolving). They were in the basement of a medical building on 6th Avenue across from Balboa Park, directly beneath a pharmacy. Thus, as one announcer put it, "the entire station is under drugs."
Sometime in the late 60's San Diego's famed blues radio/used record sale guru Lou Curtiss started doing a Sunday night blues show on KPRI.
KPRI really was an innovative FM radio station, being one of the first stations on the West Coast to go with the hippy psychedelic freeform underground programming, and for a long time they did it very well. It continued to be a fairly hip place until the late 70's when Jesse Bullet (formerly of KGB-FM) became PD and started dumbing down the station.
I recally that the Dead were doing two nights of concerts in San Diego when they were touring for
Shakedown Street. Bob Weir came into the station and I did a taped interview with him. I used segments of it during my afternoon newscasts including one bit where he was talking about playing with the Dead and beneath that I used the long intro to Playin' With The Band and just as Weir finished talking, the band jumps in singing, "Playin....playin with the band." It sounded way cool.
Well Bullet calls me on the carpet for that, says we "gotta think about that 24 year old media buyer at the ad agencies....is this the kind of thing she wants to here?" KPRI at the time was doing very well and it was because it was still a hip radio station, but Bullet always got scared whenever any station of his became successful and kept "fine tuning, fine tuning," which meant he screwed with it so it was no longer the station that people had flocked to. If you look at his later record as PD it's hard to find any lasting success: he could turn a station around, yes, but he could not sustain success.
KPRI really started to slide when the folks who owned it purchased KOGO and the corporate/focus group/computer-generated-playlist mentality started to infect the place.
Oh: a fun sidenote to the Bob Weir interview. Those of at the station who wanted them had tickets to the second night of the Dead show. Weir told me they were having a little party after the concert and did I want to come? Gee...party with the Dead??????? That's a tough choice
I took a friend to the concert and he brought along some big old doobs rolled from the finest homegrown and there was a full bar at the concert so we sat there groovin' on the Dead, tokin' big numbers and sippin' Jack Daniels on the rocks (kids do not try this at home). After the concert I'd arranged to meet Bob Weir in the bar at the Westgate Hotel across the street. The three of us hung out there for a while, listening to members of the Civic Light Opera (which also a had a concert that night) singing show and light opera tunes to the accompaniment of the piano bar guy. Then we went up to a suite and a small party attended by every member of the Dead, except Garcia, a few of us from KPRI, some Deadheads and various relatives and crew from the dead touring party. Needless to say, after Bullet's lecture on not being hip, I did not mention any of this on the air.
