In the early 70's, jazz pianist and composer Hiromasa 'Colgen' SUZUKI and his self-titled trio (with Kunimitsu INABA on bass and Hideo SEKINE on drums) started working on a project of musicians which should have made a lengthy series of concept albums mixing jazz rock and world music called ROCK JOINT.
Musicians that worked around this albums were more of jazz background and some of the musicians stayed in the line-up of both albums released as ROCK JOINT projects even though the style of music was slightly different; first 'Rock Joint Biwa' was centered around the japanese instrument biwa, giving a fresh feel to album's early jazz influenced psychedelic rock (conceptually inspired by mythology in the ancient book Furukotofumi), while the second one 'Rock Joint Cither' was oriented around sitar and Indian music (cither being a mistranslation of sitar).
