The Gerogerigegege was a japaneese penformance art and noise project.
This ambient piano piece improvised by frontman Juntaro Yamanouchi is the title track of the limited CD, Hell Driver.
If you like this, you might like their other album, "Endless Humiliation" which is an hour of piano improv and a japaneese homeless man yelling in the street.
JUNTARO COME BACK TO LIFE
