Asturias was a Japanese band formed in 1987 and dissolved in 1993. Their music can be described as a form of acoustic progressive rock. Asturias leader Yoh Ohyama was born in Tokyo in 1962. Asturias became an official project in 1987, with album releases of Circle in the Forest (1988), Brilliant Streams (1990), and Cryptogam Illusion (1993) through King Records. On these three albums Yoh performed on a number of instruments himself on most of the tracks, in the style of a solo project with guests, which included prominent musicians in prog circles.
