Music
Much of the music used on Circle of Willis comes from a single source--the music of classic Tucson alternative rock/pop band, THE NEW DRAKES (formerly just "The Drakes"), whose core writing team is Tom Stauffer and Gene Ruley. I've been a fan of these guys since I moved to Tucson for graduate school in 1996, and it was thrilling to me when they gave me permission to use their music for the podcast.
For a little background on this band, whose "collective talent and creativity ... always far exceeded its financial success," check out this 2007 piece from the Tucson Weekly.
