On May 19, 2004, Rollins began hosting a weekly radio show, "Harmony in My Head", on Indie 103.1 radio in Los Angeles. The show aired every Monday evening, with Rollins playing music ranging from early rock and jump blues to hard rock, blues rock, folk rock, punk rock, heavy metal and rockabilly, and touching on hip hop, jazz, world music, reggae, classical music and more. "Harmony in my Head" often emphasizes B-sides, live bootlegs and other rarities, and nearly every episode has featured a song either by the Beastie Boys or British group The Fall.
