UNCHAIN was formed in Kyoto in 1996.
Tanigawa (vo>), Tani (ba), and Yoshida (dr) were classmates in their junior high school. Later, Sato (gt) who was their junior, joined the band. In few years they moved into Osaka and began playing live gigs there. Taking influence from jazz, blues, fusion, soul, funk, rock, pop to groove, with a high pitched back up singer and a milder one for a frontman it really helps the band with vocals, as does the great work they do on the songs instrumentals
