And again WFMU.org if you like folk try Shrunken Planet with Jeffrey Davison Saturday mornings at 6am or just check out his archived shows. For Gospel (I mean really great americana gospel) try WFMUs Sinner's Crossroads with Kevin Nutt etc.... WFMU has it all....If you are interested in a specific genre of music, let me know, I will try to direct you.

Don't forget! All three stations could use some $ support .... Art.... The best investment you could ever make!
