SULFURIC ACID was created in 2002 by MASAKI (ex Back Bone) on vocals and TOMOZO on guitar. Later, the two were joined by SEIJI (ex CANVASE) on drums. SULFURIC ACID also started off having the support members Koji (ex :Kaluma; guitars) and Yu-u (bass). SULFURIC ACID's first live was held in October but it was a secret live and it's hard to find any information about it. In February 2003, the band held their first oneman concert.
