Ｓｃｈｗａｒｚ Ｓｔｅｉｎ (シュヴァルツ・シュタイン/shuvarutsu shutain) was a Japanese electronic band, formed by Hora and Kaya in 2001 (as “Rudolf Steiner”) and disbanded in 2004. After disbanding, they made another album together under the name another cell. Even though it is made up primarily of songs from Hora’s solo career, Hora consideres it to be Kaya’s album. They are both still in the music scene, working as solo artists.
Prior to forming Rudolf Steiner, Kaya, under the name ”姫” (ひめ/Hime) sang for the band Isola. Hora worked with Velvet Eden.
