Jonathan Scott brings the fascinating story of recorded sound with ”Into the Groove”

Cylinder recorders, 78s, 45s, and 33mph records all had a wild beginning. Inventors of all kinds and nations, all sorts of materials, and all kinds of speakers, musicians and engineers: their stories are here and lots of fun. I've been in radio since 1972 but I never knew most of this history, so I loved this book!   (As of Nov.2024 it's now available in paperback!)
