[3] For four decades, it was classical music station KXTR, first owned by Telesound Broadcasting, and initially operating at 58,500 watts.

[a] The next day, it refocused as a modern AC station, as well as introducing a new morning show, "The Kenny & Afentra Showgram".

Fans gathered to "Save The Buzz", showing a huge turnout and solidifying the station's alternative format.

On September 8, morning co-host Danny Boi announced plans to leave the show and the station.

[21][22] On August 25, 2008, both "Afentra's Big Fat Morning Buzz" and "The Church of Lazlo" returned live to Kansas City.

[23] In 2014, the station was forced to pay $1 million in a defamation lawsuit that spawned from comments made on the morning show.

The move came after Entercom initiated airstaff cuts at their country and alternative formatted stations nationwide, which included morning host Jordin Silver (who would return to the station in April 2022 to host middays remotely from Los Angeles) and night host/"The Church of Lazlo" producer Hartzell Gray (who has since returned to Audacy) being let go.

KRBZ began airing Stryker & Klein (later renamed Klein & Ally) and Megan Holiday from sister KROQ in Los Angeles for mornings and middays, and Kevan Kenney and Bryce Segall from WNYL in New York City for nights and overnights, respectively.

In addition, "The Church of Lazlo" remained in afternoons, though it would be syndicated to sister stations in Dallas, Detroit, and Las Vegas; also, former midday host Jeriney became a co-host (she has since left the station, and has been replaced by former "Church of Lazlo" co-host Snowcone).

[28][29][30][31] In addition, longtime specialty programs such as "Homegrown Buzz", "Resurrection Sunday", "Lazlo's Hardrive", and "Sonic Spectrum" were dropped.

On November 15, 2021, KRBZ dropped Klein & Ally, as the show ended syndication to focus on their local audience in Los Angeles.

At 6 p.m. on August 14, following the end of that day's Lazlo broadcast (and after playing "Last Goodbye" by Jeff Buckley; the last song as an alternative station prior to the Lazlo simulcast was Weezer’s "Say It Ain't So"), both KRBZ and KCSP began stunting, running announcements teasing the new format and running podcast-style monologues on notable teams in Kansas City sports history, beginning and ending with the 2023 Chiefs winning Super Bowl LVIII.

"The Fan" officially launched at 6 a.m. on August 15 on both 96.5 FM and 610 AM; by this time the KFNZ-FM call sign went into effect.
