Answer by taking a quote from the following article:

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 was born in St. Joseph's Hospital in Midorigaoka, Japan, on December 13, 1964 and went on to attend Yokosuka Tokiwa Junior High School. He was first exposed to rock music at the age of fifteen, through the album Alive! by Kiss. That same year his grandmother bought him his first electric guitar, a Gibson Les Paul Deluxe.  On March 11, 1980, hide graduated from Tokiwa Junior High School. He then entered Zushi Kaisei Senior High School in Zushi, Kanagawa, where he entered the school's brass band as a club activity. He quit the band after a short time because he was assigned the clarinet while he wanted to play the trumpet. After this, he concentrated on guitar and in 1981 formed the band Saber Tiger. A year after their founding, they started playing shows at live houses in Yokosuka, such as Rock City.  In April 1983 he started studying cosmetology and fashion at the Hollywood University of Beauty and Fashion in present-day Roppongi Hills, from which he graduated in 1984. Later that year he took a nationwide examination and successfully obtained a beautician license. In July 1985 Saber Tiger released their self-titled EP, which included two songs, "Double Cross" and "Gold Digger". In November, the band contributed the song "Vampire" to the Heavy Metal Force III sampler, which also included songs by X and Jewel. Years later, Jewel's guitarist Kiyoshi would join hide's solo band.  In 1986 the group changed its name to Saver Tiger to avoid confusion with a similarly named band from Sapporo (see Saber Tiger). Their first appearance with the new name was on the sampler Devil Must Be Driven out with Devil, with their songs "Dead Angle" and "Emergency Express". They continued to perform in live houses and night clubs such as Meguro Rokumeikan, Omiya Freaks and Meguro Live Station. Until January 28, 1987, when hide became tired of changing members and decided to end the band (vocalist Kyo and drummer Tetsu would both go on to D'erlanger). Around the same time hide was invited to join X. In 2001, Nippon Crown issued a three-volume release titled Origin of hide, with the band credited as "Yokosuka Saver Tiger". Volumes 1 and 2 were live CDs, with some rehearsal recordings, while volume 3 was a concert VHS.
