Following the release of the 2nd album, Nadir (2002), the group changed all members but Hideshi Ueki, and performed at World Rock Fest in August, 2003, held by the Universiade in South Korea.

The 3rd album, Fortune Missionary (2004), and 4th record, Signs (2006) followed next.
In 2014, RMG changed into a solo project of Hideshi Ueki with first-rate support members: singer Sunghoon Kim from South Korea, bassist Kaz Nakamura of Kelly Simonz’s Blind Faith, keyboardist Takumi Matsubara and a session drummer. After writing new songs for the new album, they got down to pre-production in early 2016. Seeking for vivid acoustic sounds, they started recordings at Tapestry Recording Studio with engineer Fuyuhiko Inui in July, where Japanese bands like Solitude, Outrage and United have recorded as well. While Shinya Tange produced the drum sounds, Yusuke Abe from OUTRAGE and Saeko Kitamae also guested in some songs. Last but not least, they got Alessandro Del Vecchio (Hardline) to mix and master their songs.

A concert with Circus Maximus from Norway followed in Nagoya Japan later that year. In the meantime, the group has developed from a “neo classical HM band” to a “progressive melodic HM’ band.
