The band was formed in 1990. Their 1991 song "Hanashitaku wa Nai" (lit. "I do not want to release you") became a hit song in the cable broadcast. [ 2 ] After this success, the band released several hit songs and albums. Their 1993 song "Osaekirenai Kono Kimochi" (lit. "Inextinguishable This Heart") was used for the ending theme of Ichigo Hakusho (in which then-unknown Namie Amuro played a role). The single reached number 1 on the Japanese Oricon weekly charts, becoming their first number-one single. However, Morimoto suffered throat problems so his doctor advised that he should give up singing. Despite this, he was forced to perform a live concert on March 26, 1995. It became their final concert. After a long hiatus, the band officially disbanded in December 1999.
