Jim Ladd presented his shows in a freeform manner, interrupting the regular classic rock format during his show middays and Sunday evenings. Ladd picked the music personally, often based on listener requests, and played it in thematic sets. On Wednesday nights at midnight, Ladd devoted an hour to "Headsets", which combines music with a slightly more "sonic" quality (designed to be heard with headphones, or with no background noise interfering), spoken-word poetry, and audio clips from movies and television. On Sundays, Ladd presented "Theme of Consciousness", with all songs within a three-hour window devoted to a singular word or "theme" and chosen entirely by the listening audience. In addition to his work with KLOS, Ladd also appeared on KNAC during its progressive era, KMET, and KLSX. Often dubbed "The Last DJ", after the Tom Petty song that was written about him, Ladd was allowed unusual latitude in selecting the music for his program. His show was routinely the number-one music-based show in its time slot. Ladd left KLOS in October 2011 and joined SiriusXM the following January, hosting daily on the Deep Tracks channel.
