The 106.7 FM lineage began June 19, 1962 as KLZ-FM, the FM sister of KLZ 560. It initially simulcast the AM station. Broadcast Pioneers of Colorado notes that this was actually KLZ’s second FM venture: an earlier KLZ-FM had operated on 94.1 beginning in the summer of 1947 before disappearing from trade listings in the mid-1950s.
The revived 106.7 facility became an important Denver rock outlet. In 1977 the call letters changed to KAZY, which continued with mainstream and album-oriented rock and became one of Denver’s best-known FM rock stations.
On April 20, 1994, KBPI moved from 105.9 to 106.7, ending the KAZY era. The frequency later became KWBL “106.7 The Bull.”
Lineage: KLZ-FM → KAZY → KBPI → KWBL.
