This is a BBC radio dramatization of A Clockwork Orange by Anthony Burgess. The book is still a shocking satire of Western culture gone to the youthful dogs of violence and mayhem. Burgess played with language by inventing a detailed and comically expressive slang for his criminal hero and the gang he leads.
The best info I can find about this recording dates it somewhere around 1997. It stars Jason Hughes as the murderous 'droog,' Alex.
