Monday Morning Audiolink One: X MINUS ONE and DIMENSION X
One of the finest radio shows of the 1950s -- you'd be hard-pressed to find a better science-fiction/fantasy radio show in any generation before or after it -- "X-1" featured adaptations of short stories from the likes of Ray Bradbury, Robert A. Heinlein, Robert Bloch, Fletcher Pratt, Isaac Asimov, Robert Sheckley, L. Sprague de Camp, Fritz Leiber, Philip K. Dick and Theodore Sturgeon. Admittedly, even the most tony and literate of these stories were still turned into sausage to be broadcast on a weekly half-hour anthology program, but the technology and sophistication of radio production had reached its apex just as X-1 made its debut. Much like silent film, radio drama had ironed out most of its kinks and its best practitioners had absolutely mastered the art form just as it collapsed and disappeared in favor of a sexier new medium [sound movies and television, respectively].
