After graduating from music school, she took an opportunity to visit Japan in 1991 and finally contracted with ROAD&SKY Organization in 1993.
She has now released six solo albums, two mini-albums, and some singles hits.
Her last album "Era of Queens" was released in november 2003 and was recorded in London.
Origa also participates in many projects of various artists in addition to Radio Japan Series and chorus for Kobe Earthquake disaster charity single and others.
She became famous outside of Japan with the release of Ghost in the Shell: Stand Alone Complex and the subsequent Original Soundtrack largely written and arranged by composer Yoko Kanno. (Origa first performed with Yoko for the Turn-A Gundam concert, performing Gabriela Robin's Moon with the Gey's AX chorus.)
The disc's centerpiece is the opening theme of the first season of Ghost in the Shell: Stand Alone Complex, Inner Universe, a beautiful, high-energy piece featuring English and Russian vocals by Origa (being backed up by boy soprano Benedict Delmaestro and Japanese-French vocalist Shanti Snyder, who was also co-lyricist on the song with Origa).
Ghost in the Shell: Stand Alone Complex 2nd GIG (Season 2) features Rise as the opening, another song written by Yoko Kanno and performed by Origa. The featured voices in Rise are credited to Tim Jensen and Ilaria Graziano.
