This acid jazz trio was formed in 1999 and has consisted of Jinu (bass and programming), Jo Won-sun (lead vocals and keyboards) and Lee Sang-soon (guitar) from its formation to the present day. They are pioneers of acid jazz in their home country, where the genre was previously non-existent.

Prior to co-founding Roller Coaster, Jinu worked together with musicians such as Lee Seung-hwan and Yoo Hee-yeol. Jinu also performed as a solo singer. Before debuting as a member of Roller Coaster, Jo Won-sun variously sang and played keyboards on records for Yoon Jong-shin, Lee Hyun-woo and Yang Hyun-seok. Lee Sang-soon was also a highly regarded musician before joining Roller Coaster, having been with the band Baby Blue.
