BBC Radio 4 Extra always runs some great radio plays; this week alone you can hear Terry Pratchett’s Wyrd Systers and a series of short Sci-Fi stories turned into audio books on Brian Aldus Presents. If you hit their Schedule for this week you can hit Monday and start from the beginning, as they let you listen to shows for the next six days after they air. Coming up on Saturday there is a program called Alexander Armstrong’s Radio Heroes, which will include classic episodes of radio dramas like Journey Into Space and Judge Dredd for your enjoyment. I spend an average of 7 hours a week listening to programs on this service, it always has some fun and interesting science fiction and fantasy.
