In October of 1967 they dropped that free form mess and flipped to what they called "Rock-Jazz." Billboard,dumbfounded, ran a very short article the change. Billboard's description of it as Rock-Jazz seems comical now of course but maybe not at the time. Some of that later hot jazz was just as rambunctious as rock n' roll. This website explained it thusly:
"It was the epitome of underground radio in the early days. It was an FM station that was so low powered that they had to run promos on how to construct home antenae that were the right length to receive the signal!! This was done with cool moog synthesizer music in the background."But later references to the station indicate they were still playing progressive rock in 1968. Rock-Jazz, whatever it was, died in 1968. Under Crawford broadcasting it became a Southern Gospel station and then a Contemporary Christian station. They sold it in 1979 to First Media who flipped it to an oldies/ Soft AC mix. That odd mix hung on through most of the 80s even being decribed by Billboard in 1989 as an "oldies Top 40 blend."The KFMK calls currently reside just outside Austin now on 105.9. More here.
