Podcast Directory has a great guide to past episodes of Indie Night School including brief descriptions with who’s on the podcast and who they work with:
INS is a music conference series that deals with all the many aspects of running a band professionally, independently, successfully, and ethically. The panels give people the chance to meet decision-makers who run the music industry, ask them down-to-earth questions, and receive straightforward answers. Each session seeks to explicate a different aspect of the music industry, such as how the A&R process works, how to find (or become) a band manager, how to get online and print publicity, and how to find legal representation.

The descriptions are nice because the iconocastic archives simply lists them.  Be sure to check iconocastic for Hierocast, the Hieroglyphics Podcast, as well.
