Primrose was a young Japanese rock band that was active from 2002 to 2004. The band consisted of four members, 龍詩 (Ryuuji) on vocals, 夢人 (Yumehito) on guitar, 龍緋 (Tatsuhi) on bass, and Yuya on drums, though for a while, they played with a guitarist named UZ.

Members 夢人 and Yuya had been friends since a young age, and in 1998, the two started playing music together in a school band. Years later, in 2000, 夢人 met 龍緋, and in 2001, he met 龍詩. The four became friends, and in 2002, they formed their first real band, Primrose. Primrose played their first live on June 6th, and were active until the summer of 2003. In December, they started up activities again, and kept playing gigs until April of 2004, when they changed their name to そろばん.

Primrose released their first and only single, 沁月-闇-, on November 15th, 2002. The single was sold for 600¥, and was only available at lives or through mail order. Read more on Last.fm. User-contributed text is available under the Creative Commons By-SA License; additional terms may apply.
