Tom Trunnell was a Denver progressive-rock broadcaster whose work at KFML and KBPI placed him among the city’s influential early FM rock personalities.
By 1972, Billboard identified Trunnell as its Denver correspondent for progressive FM music, listing him with KFML and KBPI among programmers at leading progressive stations around the country. The role reflected a period when FM rock announcers were not simply playing established hits; they were helping introduce albums and artists to local audiences and reporting emerging music back to the national record industry.
Trunnell later became part of KBPI’s veteran free-form staff alongside Jeff Pollack, Larry Bruce, Bob Reid and Dennis Constantine. The station drew on the underground-radio tradition, allowing its personalities considerable discretion in music selection.
In 1976 that culture changed as KBPI tightened its playlist in response to KAZY’s more structured album-rock format. Constantine later recalled that the veteran staff, including Trunnell, was replaced as KBPI moved away from free-form programming. Trunnell’s documented work preserves an earlier moment in Denver FM history when individual programmers exercised unusually broad influence over what listeners discovered on the radio.
