KBLX-FM (102.9 MHz) is a commercial radio station licensed to Berkeley, California, and serving the San Francisco Bay Area.

Until its sale in April 2012, KBLX was owned for more than 30 years by the now-defunct, black-owned Inner City Broadcasting Corporation, and used the slogan "The Quiet Storm."

The station was the first to break records by Pete and Sheila Escovedo, Bill Summers, Sylvester, and other Bay Area artists.

When Inner City Broadcasting purchased the station, it eliminated the unique format and changed it to more mainstream urban sound with less interaction with local artists and the community.

Throughout the 1980s, the station played an eclectic mix of R&B, smooth jazz and soft pop, reflecting the diverse music culture of the Bay Area.

KBLX was the inspiration for the creation and launch of various adult contemporary radio formats across the country, from smooth jazz to soft rock to urban AC.

From then on, KBLX has evolved into a true urban AC station today, playing current and old school R&B, as well as uptempo R&B songs to match its competitors.

[2][3] Entercom officially took control of the station on May 1, 2012, and fired the entire on-air staff of KBLX (except traffic reporter Joe McConnell).

The firings included morning personality and program director Kevin Brown after 22 years, and the original general manager of the station.

To comply with FCC ownership limits, it was announced that KBLX, along with sister stations KOIT and KUFX, CBS-owned KMVQ, and a cluster in Sacramento, would be divested.
