One is Ra's debut EP and was released in 2000. The songs "End of Days" and "What I Am" were not included on their debut album From One. However, "What I Am" is included in their album Black Sheep.
One was only sold (for $10) during Ra's concerts, and soon went out of circulation when Ra's debut album From One hit stores. The EP is still available through Ra's online merchandise store, but is otherwise a rare collector's item.
In an interview with SoundCheck Magazine, Sahaj Ticotin (the lead singer) talked about One:
"It just says Ra One since it's the first CD. The theme is kind of a double meaning. The record is primarily about lonelinessâ¦different variations of loneliness. So I named it One also because of that".
