Radio like you've never heard

About Us

About Us

K4CO Radio is an internet and app streamed radio station based in Centennial, Colorado. Our mission is to play a large span of music from the 1940’s through today, with no commercials, with in-depth interviews, and four times more music than the average AM/FM corporate radio station. Keeping with the true spirit of radio, most of our content will be operated by our on-air DJ’s. It's time to make a radio station about our community, the music, and the future.


Joshua D'Estrada

On average, pre-recorded commercials are played on most AM/FM radio stations 18 minutes of every hour (that’s almost 1/3 of every hour). The rest of the time is dedicated to talk, mixed with the music that DJ’s are required to play. Here at K4CO, we feel music is the foundation of radio and should take up a more significant amount of time. Our DJ’s have the freedom to play a wide range of music. If you have a love for music, we are the station for you.

"The music is your special friend"

- Jim Morrison

The world of radio has been changing over the past decades. AM and FM radio stations have been focusing attention on airing an excessive amount of commercials and playing only a select group of songs that they push to their listeners. Today it is no wonder you hear the same song repeated on multiple radio stations. Many incredible artists with extensive catalogues are reduced to a handful of songs (if not only one or two). A majority of great musicians’ catalogues cease to exist in today's world of broadcast radio.

"Music drives you. It wakes you up, it gets you pumping. And, at the end of the day, the correct tune will chill you down"

- Dimebag Darrell

Kevin Stanley
Station Manager

At K4CO Radio, we believe it is time to make a drastic change and create a concept of what radio should be: a platform spanning many years and genres of music, combined with a community of dedicated listeners and partnerships. Internet radio, in the US, has grown an average of 8.4% per year since 2018. There are many different types of internet radio, and we want to bring back the old feel of radio, with more focus on music and community. It is time to accept that times are changing, and bring radio into the future.

"To hell with the rules. If it sounds right, then it is"

- Eddie Van Halen
