KJZY was begun in 1995 by Gordon Zlot, and remains under the ownership of his company, Redwood Empire Stereocasters, into 2006. The station plays smooth jazz, featuring contemporary artists like Dave Koz, Wayman Tisdale, David Benoit, Mindi Abair and Lee Ritenour, and classic artists like Ramsey Lewis and Wes Montgomery. Music Director Rob Singleton believes modern smooth jazz "is the evolution of fusion—milder fusion, the original fusion was pretty electric."
Specialty programming includes "The Groove Boutique" (hosted by New York disc jockey Rafe Gomez), "Swingin' With Sinatra", "The Dave Koz Radio Show" and "Jazz with Jerry Dean". News is delivered in a brief, headline-style format during morning drive time.
