Mind Webs was a 1970's series out of WHA Radio in Wisconsin that featured weekly short stories of science fiction by some of the genre's best writers. The music, sound cues and occasional character voices along with the performance of Michael Hansen, the reader, resulted in better than most fully dramatized productions of the period. Around 150 shows were aired between 1976 and 1984 varying in length, but most were about 30 minutes.
