I have been told that several Iain M Banks short stories have been adapted for radio, probably broadcast by the BBC. Hunting online all I can find is a reference to an adaptation of "The State of The Art". Wikipedia states that radio adaptations of "Espedair Street" and "The Business" have been produced but I see no reference to any other short stories. Wikipedia sometimes has gaps so I am curious to know if anyone out there has additional information or can confirm this is the only story produced.
The BBC recorded a full cast audio of the titular work, The State of the Art in 2009.
A version of the urban fantasy The Business was recorded (and scored) by Paul Oakenfold as part of his books-to-music series on Galaxy FM in 1999.
An abridgement of The Business was also created for BBC Radio 4 in 2010, presumably to fit a book review segment.
Aside from this, none of his other science fiction/fantasy works appear to have been recorded for radio, although some of his other fiction books and short stories (Piece, The Crow Road, The Wasp Factory and Espedair Street, for example) have been seen.
