During the 1970s, KBPI gained press for inviting people to bring their disco records to the station office for destruction, and this was frequently broadcast live over the air to the tune of Black Sabbath songs.

For four years, Steven B. and the Hawk ruled the Denver morning FM ratings, mixing rock music with their witty comments and routines.

They created their own ongoing series, whose titles were partially taken from the real shows that aired at the time: Edge of Guiding Days of My Children Turning Hospital.

Steven B. Williams, who had become a nationally prominent voiceover artist for television stations and networks including Nick at Nite and moved to California, was found dead of a gunshot wound in May 2006 off Catalina Island,[5] and a business associate who embezzled the inheritance of Williams's father was convicted of his murder in 2011.

[6] On April 20, 1994, Chancellor Media moved KBPI to 106.7 FM, which had been the home of KAZY, its long-time rock competitor and a former sister station to KLZ-AM-TV.

[7] Notable DJs include Willie B., DMac, Marc Stout, Scoop, Missy, Uncle Nasty, Matt Need, Double A Ron, Dan, Tim Bourke, Eddie, Joe the Russian and B Lo.

In 1977, KLZ-FM changed its call sign to KAZY (now at 93.7 FM in Cheyenne, Wyoming) and continued with a rock format until KBPI moved to the frequency on April 20, 1994 (105.9 would then flip to hot AC as KALC).

In 1996, the duo and two other station employees were charged with disorderly conduct for entering a mosque while playing "The Star-Spangled Banner" on a trumpet and trombone.

The previous 106.7 signal, which warehoused the KYWY call letters, simulcasted KBPI for a week before flipping to country as KWBL on December 18, 2017.

[13][14] KBPL partially broke away from the trimulcast in January 2019, reintroducing local hosts in the afternoon and nighttime dayparts, and carrying a separate playlist.
