Query: Broad approach

This book covers a large scope of musicians and technicians who were involved in electronic and electric music from the early 1900's to the present day. It is written in a fairly comprihensive style and centres upon the impacts that technology has had upon c20 music. A facinating read. Highly recommended for broad insights into the intentions of most electronic composers. I was rather happy to see a brief section on DJ Olive actually - this shows that Homles does not merely wish to stick to mentioning composers that the masses often only know by name. Splendid stuff. Couldn't find much wrong with it really. Take a preview of the contents page for yourself for a general idea.
