Hideto Matsumoto , known professionally as hide, was a Japanese musician, singer, songwriter, and record producer. He achieved international fame as the lead guitarist of the rock band X Japan from 1987 to 1997 and a solo artist from 1993 onward. He also formed the United States-based rock supergroup Zilch in 1996.

X Japan is a Japanese rock band from Chiba, formed in 1982 by drummer and pianist Yoshiki and lead vocalist Toshi. Starting as a predominantly power/speed metal band with heavy symphonic elements, they later gravitated towards a progressive sound with an emphasis on ballads. Besides being one of the first Japanese acts to achieve mainstream success while on an independent label, the group is widely credited as one of the pioneers of visual kei, a movement among Japanese musicians comparable to Western glam.
