Released in 2006, "brainwave music" offers a unique musical experience by David Rosenboom. This is a fairly famous album in experimental music. It is out of print and likely quite difficult to obtain. The obi and jacket are still in beautiful condition. The jewel case is also not cracked. Furthermore, although I couldn't photograph it due to reflections, there are no scratches on the disc surface. Thank you. - Title: brainwave music - Artist: david rosenboom - Tracks: 1.
