140 pages that give you a rock solid foundation to go as far as you want with music. If that sounds a bit much to handle, only the first 5 chapters are crucial, the rest is up to you how far you want to take it. I just figured you'd want to know about FX and Microphones. An interesting wee statistic is that 20% of the musicians I surveyeed cant even use a computer! - So I included a chapter on the real basics because they are no less talented, they just need to get over it. I believe it is only a hindrence to their potential contribution to music. This book is well set out and easy to read.
