There are a number of historical articles about the legendary KSFR, San Francisco.  Under the direction of its founder Al Levitt, KSFR was a luxuriantly creative classical music station at 94.9 MHz on FM.

The first air date was March 11, 1958. The Bay Area Radio Museum presents an historical article here including a sign-on audio sample circa 1959.  Also, you can visit the Wikipedia KSAN-FM article for more history.

On June 1, 1962 KSFR became the first San Francisco Bay Area station to broadcast classical music in stereo.

The move from classical to the new KSAN rock music format was a notable San Francisco event for all its implications.  It took place on May 21, 1968 at midnight.  For the first time on the Internet, you can listen to this historic transition using link at top of page.  Steve Miller Band's "We are children of the future..." line prophetically portends a media diversification and openness trend that continues now decades later.  The midnight clip explicitly contrasts what was and what will be.   The original recording quality is adequate but unfortunately not excellent.

A company called Levitt Ventures was set up to produce creative radio advertising for businesses.  Below are two Real Audio streams taken from an LP made to display the available services.  The innovative spot samples were aired on KSFR and perhaps in other venues:

Levitt Ventures production work sampler 1 (31:14)

Levitt Ventures production work sampler 2 (3:43)

You can hear the full bloom of Al Levitt's creative talents in the two clips.  Note the exaggerated effects used to show off the marvel of FM multiplex stereo.  That was probably quite common in the early days of production for stereo FM.

Al Levitt passed away shortly after the transition to rock music on KSAN.  The cause of death at age 42 was never publically disclosed, and not much more was said about him as the years have gone by.  Those who enjoyed and were dazzled by his genius via KSFR will surely never forget him.
