Jo Sims (Facebook photo)
Eris Radio recently did a podcast on "Music For Discordians- Stylings Of Jo Sims." The host, Sean Lawless, read quotes from Robert Anton Wilson and Robert Shea and played Sims' music. She is a singer and has performed with Planet Nine and Dorothy's Ghost, which I believe is her current group.
I liked her voice and the songs. My favorite tune was "Close To Me" by Dorothy's Ghost, available here.
