Sometimes you get the music, a cover and little else if you receive music in download form. A web search turned up nil. So I have nothing to go on here except my ears.
The music, seven works in all, is quiet in the manner of Morton Feldman. The tonality is loosely chromatic, tied to a key but tenuously. Unlike Feldman's later work there is no obvious pattern of repetition, which of course is fine. Instead we have a linear progression of unfolding, sparse melody, which strikes me as somewhat mystical, perhaps a bit Zen-like in its revelling in the sensuous sound moments in succession.
Pianist Satoko Inoue gives us a sensitive reading. The music haunts our sensibilities and then is gone. We are left with a feeling of peace, but not with a new ager's attempt to force that peace upon us. This music has authentic sensibilities. If you love Feldman this will be in your wheelhouse. It revels in understatement. I would love to hear more of Satoshi Tanaka! Recommended.
