My name is Mary Tilson. I'm a member of KPFA's music department and produce "America's Back 40" an American roots program heard on Sunday's at 1pm. I've been associated with KPFA as a broadcaster since 1981. I also was employed by the Pacifica Foundation from 1987-1999 where I provided a wide variety of administrative and fundraising services to the network. I have worked in a variety of alternative commercial radio settings ( WUPY, KFAT) and community and public radio stations ( WNMU, KALW) in addition to KPFA.
