Ryuichi Sakamoto, one of the pioneering figures of Japanese electronic music, demonstrates his versatility on this change-of-pace album. Released in 2004, 04 is dominated by Sakamoto's prowess on the acoustic piano, and features excerpts from several of his scores for motion pictures (including his music for Merry Christmas, Mr. Lawrence), television commercials (such as a campaign for Louis Vuitton), and video games ("Seven Samurai: Ending Theme" was composed for the PS2 game Seven Samurai 20XX).
