Tape Leaders - A Compendium of Early British Electronic Music Composers - for the past 3 years Ian has been researching and writing this ambitious book which is due for publication by the end of this year. The A-Z is designed as an essential reference guide to British based composers who created experimental work with electronics and tape - concentrating on the formative electronic music period during the 1950s and 60s. The aim is to document every serious composer and as many amateurs as possible, who created an experimental tape piece up to 1970, and thus tell the hidden story of early British electronic music.
