From the 1960s to the 1980s, the rock radio DJ played an unprecedented creative role in the music world. I AM WHAT I PLAY profiles four DJs in major markets during this period: their programming, their politics, and their deep connections with musicians and fans in the heyday of rock radio. Where are they now, and how did they reinvent themselves as the medium changed?

I Am What I Play combines material shot on location in the 4 cities (Seattle, Boston, New York and Toronto) with rarely seen archival footage of the disc jockeys, the radio stations and well-known rock performers, all complemented by a soundtrack that features many great rock songs of the era.
