This game, as well as the first one (on ps1), is full of psychedelic awesomeness. It is a rhythm game for ps2 not unlike Space Channel 5. And from the first moment on you feel it is one from the days when those games still had the freedom to aim for pleasing a niche audience instead of everyone and their parents. Another one for the list of stoner game classics.
The second video shows you some of the gameplay and the third one is a song from the game but looks just like a very cute music video.
