I have recently been in contact with Mike McDonough, the award-winning sound designer and writer-producer of the classic radio series Bradbury 13. Mike was kind enough to answer some of my questions, which has enabled me to expand my page on the series.
Although episodes of the series were once available on audio cassette, there has never been a CD release of the show. Aficionados have had to make do with relatively poor quality recordings, many of them unauthorised. The good news is that Mike is still in possession of the original studio master recordings (and the copyright on the series), and has recently transferred them to a digital format to preserve them for posterity. He still hopes that he can one day secure a commercial release on CD, or as high-quality, official MP3 downloads.
