Sharam Q

Sharam Q was a Japanese rock band composed of lead singer Tsunku (つんく), Hatake (はたけ) on guitar, Makoto (まこと) on drums, and Taisei (たいせい, たいせー prior to 2006) on keyboards. There also used to be a former member called Shu (しゅう) on bass, who was in the band since its formation until 1998, due to two cases of sexual assault. Following the announcement of Tsunku's vocal cords removal, the band disbanded in 2015. (Source: Wikipedia)
