In 1988, KBCO Studio C was created by Production Director Tom Koetting with a performance by Melissa Etheridge in a small cramped production studio. The studio was later upgraded, and many artists in Colorado for a concert tour or promotion tour would stop by to play live on the radio. The station releases a CD every year in late November with the best or most memorable Studio C performances. The CDs, titled "KBCO Studio C" followed by the volume number, sell out quickly and all proceeds from the album are donated to the Boulder County AIDS Project and Food Bank of the Rockies. Two retrospective CDs have been released combining the best of the previous CDs and several unreleased songs.
