Delaware is, by their own definition, a "Japanese supersonic group [that] designs-rocks and rocks-designs." They also call themselves "Artoonists." Since 1993, the collaborative has displayed their retro-futurism across a range of contemporary products, including music CDs, CD-ROMs, commercials, magazines, T-shirts, websites, live shows, and mobile phones. Delaware is four: Masato Samata, tape recordist, vocalist, lyricist, composer, art director, and designer; Aya Honda, bassist, vocalist, composer, and designer; Morihiro Tajiri, guitarist, bassist, drummer, vocalist, composer, and recordist; and Yoshiki Watanabe, guitarist, vocalist, sound programmer, phone ringer, and composer.
