In the previous work "Free Music1960 80: Anthology of Open Music", we originally planned to feature about 1,000 albums from 1960 to 2000, but since the contents of the book was up to 1980, we could introduce only 166 albums as Disk Guide in the latter half of the book and could not introduce other many albums. Therefore, from that experience, we decided to independently publish the Disk Guide part as a sequel to the previous work, adding 234 albums to the 166 albums already introduced in "Fee music1960 80" and featuring a total of 401 albums. And The title of the book was renamed "freeJazz & Freemusic" and published.
