Right. Just bought some decks and don't know what to do with them? This is the book. I was in that position, and worried about a) being patronised (I play a number of instruments quite well), or b) bored to death by a squillion obscure labels for music I don't like (happy euro trance etc.). Having looked about, this was the only DJ book on Amazon with no negative feedback, and it's for a reason; it really is very very good, for anybody at practically any level (unless you're Cash Money or somebody). Tells you literally everything (technique, technical stuff, business, music industry), doesn't talk down to you, doesn't obsess about style. The authors tell you again and again that it's all about the music, so if that's how you're looking at it as well, I can't recommend it highly enough.
