From the artist’s description:
Tristan Perich’s 1-Bit Symphony is an electronic composition in five movements on a single microchip. Though housed in a CD jewel case, 1-Bit Symphony is not a recording in the traditional sense; it literally “performs” its music live when turned on. A complete electronic circuit — programmed by the artist and assembled by hand — plays the music through a headphone jack mounted into the case itself.
1-Bit Symphony was released on August 24, 2010 by Cantaloupe Music.
