I thought the books looked quite heavy with theory taught in an unconventional way e.g. the diagrams.? (By the way, your link doesn't work - I had to search for the author on Amazon.? I would be put off by some of the negative reviews on Amazon.? Some of these can be written by people who aren't really advanced enough to tackle a particular book; but I'm not sure that there's any answer to the criticism that there no recorded examples of the author's own improvisations to be found anywhere.? It would be interesting if anybody on this group has read any of his books.? I just noticed from his website that he has done some books with transcriptions of John Coltrane and Sonny Rollins solo and a Bird Real Book (with heads by Charlie Parker).? So I may be interested in getting the Coltrane book since it is for C instruments.? (The Sonny Rollins one is for Bb instruments.)? There does appear to be one album by Masaya Yamaguchi linked from his website (on the page linked from "music" on the navigation bar type thing on the right hand side of each page)?
