"Parasitic Infestation" was originally written as an introduction to The Art Of Worms, The Bookworm’s debut publication documenting the cover art for The Tapeworm’s first 25 cassette releases. The book was launched at an event called Worm Eats Bear on 20 October 2011 at London's Bear Pit, where this recording of Hollings reading his essay was made.

The Art Of Worms is currently out of print, but you can read the complete text here. Works For Magnetic Tape is released by The Tapeworm in October
