Hideto Matsumoto (Song Ben  Xiu Ren , Matsumoto Hideto, December 13, 1964 - May 2, 1998), better known by his stage name hide, was a Japanese musician, singer and songwriter. He is primarily known for his work as lead guitarist of the heavy metal band X Japan.

hide joined X Japan (then called X) in February 1987, becoming the band's lead guitarist and occasional songwriter, going on to compose songs like "Celebration", "Joker" and the single "Scars". X released their first album Vanishing Vision, through drummer Yoshiki's own Extasy Records, on April 14, 1988 and toured extensively in support of the record. They would become one of the first Japanese acts to achieve mainstream success while on an independent label, and later widely credited as one of the pioneers of visual kei.  X 's major label debut album, Blue Blood, was released on April 21, 1989 and debuted at number six on the Oricon chart. Its success earned the band the "Grand Prix New Artist of the Year" award at the 4th annual Japan Gold Disc Awards in 1990. Their third album Jealousy was released on July 1, 1991 and debuted at number one, selling over 600,000 copies. It was later certified million by the RIAJ.  Shortly after the release of Art of Life, which also topped the Oricon, the members of X Japan took a break, to start solo projects. Around that time, the group also dropped most of its original visual kei aesthetics, except hide who would still perform in wildly colorful outfits and with his trademark red, later pink, hair. Dahlia, which would become the band's last album, was released on November 4, 1996 and once again, it reached the number one spot. In September 1997 it was announced that X Japan would disband, they performed their farewell show, aptly titled The Last Live, at the Tokyo Dome on December 31, 1997.
