"Music Board Improvisation. Solo Hardcore Symphony"

Some info on the MusicBoard (MBoard) via the Array Instruments website:

"A harmonic array of electronic touch buttons mounted under a smooth surface for playing music while using computers or electronic synthesizers to make the sounds. Fingers, thumbs and palms as well as hand held implements such as sticks and picks may strike pluck or strum across the playing field to activate the notes. The closest moves produce the most consonant harmonic changes."
