In the liner notes to his recent Brain Pulse Music (Drag City), Ghost guitarist Masaki Batoh writes of a decades-old dream to create music from brain waves. Composers such as Alvin Lucier and David Rosenboom, among others, have been making music from brain waves for decades, and assuming Batoh knew that, his dream was probably about access to equipment that can translate alpha waves into sound. His application of the technology is highly personal and fits well with the more primitive, ceremonial side of his music with Ghost. Oddly, of the album’s seven pieces, only two include brain-wave music; most of the tracks use traditional Japanese percussion instruments and shakuhachi.
