This item is a bit of an oddity. It is a normal music cassette, entitled Aural Sculpture by The Stranglers (never heard of them). However, after the end of the last song on side 2 is recorded a unique text adventure for the ZX Spectrum computer, Aural Quest! Such was the popularity of the Sinclair machine throughout the UK at the time. It appears the game was written by the musicians using the popular Quill tool from Gilsoft.
