 In 1977, Yoshiki and Toshi formed a band called Dynamite in their hometown of Tateyama, Chiba, when they were just 11 years old. Dynamite changed its name to Noise in 1978, while they were still in high school. In 1982, Noise disbanded and Yoshiki and Toshi formed a new band, they named it X while they tried to think of another name, but the name stuck. X began to actively perform in the Tokyo area in 1985 with a frequently changing lineup. Their first single, "I 'll Kill You" was released on Dada Records in June and the band contributed "Break the Darkness" to the sampler Heavy Metal Force III in November, which also featured a song by Saver Tiger. In November 1985 bassist Taiji (ex: Dementia) joined X, though he left the group shortly thereafter.
