I recently bought these two books and I enjoy reading them. I will definitely recommend them to all music lovers, not only if you are a DJ.
Last Night a DJ Saved My Life, The History of the Disc Jockey
The first one is the interesting story about how it all started in the world of the disc jockey. A journey from the 60s up till ‘now’ (2012) with many fun facts and interviews with famous DJs.
(Bill Brewster & Frank Broughton, 2012)
1001 Albums You Must Hear Before You Die
The second one is an overview of epic albums in different genres. Each review includes some interesting facts about why this album was important in the history of music.
