Over the years, I've noticed Kasim's shows have been recorded and traded around with other fans. To my knowledge, there aren't many shows out there that have been recorded. Here are the shows I know about that are available on audio:
6/82-Kasim at My Father's Place, NY
1/87-Price/Sulton radio show, NYC
7/4/05-show from England
8/19/06-New Haven, CT
I'm looking for Kasim's shows from 1980 and radio shows and interviews he's done by himself and with Utopia.
