Brain Pulse Music

Former Ghost member Masaki Batoh released Brain Pulse Music, a collection of prayers and requiems for the victims of the earthquake and tsunami, featuring traditional instruments as well as two brain-controlled electronic devices called BPM.
The album is out on Drag City and the machines themselves are on sale as well for $699.
There's a nice article about the project on Wired. Proceeds go to the Japanese Red Cross.
