Mindwebs is an excellent radio show that originally aired on WHA Radio in Madison, Wisconsin from the mid 70’s through the mid 90’s. It lasted for over 160 episodes and featured Michael Hanson expertly reading stories by over 130 authors, many of which are well-known authors from Sci-Fi’s golden age.
There is an effort going on right now to resurrect and remaster all 160+ episodes from Michael Hanson’s own tapes which they are then releasing for free on the Archive.org. These episodes come from that effort and are significantly higher quality than what could be found before.
I highly recommend this Mindwebs and encourage you to visit the project’s page over at the Archive.org
