It is always a joy to come across something one does not know enough about, and I have recent.ly written two book reviews for Organised Sound. Jennifer Iverson’s book discusses the post-WWII landscape especially in electronic music, and Leigh Landy’s book is a music appreciation and listening guide for many types of technology-based music. The review of Iverson’s bok is here, and the review of Landy’s book will be published later this year.
