One of the most famous artists that came to light from the Swedish underground scene is the keyboardist Bo Hansson. His album "Lord of the Rings" inspired by the book of the same name remains a staple for all the freaks of the seventies and was internationally successful. "Lord Of The Rings" or "Sagam Om Ringen" remains a pre new age masterpiece of instrumental music for the mind, with splendid moog and organ releases, which underline Hansson's jazz origin, for four years and only until the first one with drummer Janne Carlsson for 3 albums of floating psychedelia and boogaloo.
