A guide book that introduces masterpieces and hidden gems of ambient music released over the past 55 years, from 1958 to 2013.

A carefully selected 332 images from ``Ambient Music'' and ``Ura Ambient Music'' published by Infas in 2009, with 407 new additions, and like ``TECHNO definitive'', all 250 pages are in color.

Just looking at the more than 700 ambient album covers is a great feeling, and there are so many hidden gems in ambient music, so there are surprisingly many things that are unknown, and that's why there's so much to look forward to. It makes me happy that there are still albums that I want to listen to so much.
