This is a Japanese formation which is defined as a group of Hardcore Progressive Jazz (yes, it is not invented).
It is especially important and effective variable in time, brass, electric guitars, a Sythe, battery and other peripheral instruments that come and go over the different public services.
This CD is a live played mid-2000s and absolutely awesome quality. The quality is close to a studio quality, with all the spontaneity and passion of a summer live. A rare find in any genre.
