A slideshow of the legendary Hanatarash-concert on 8 – 4 – 1985: http://www5a.biglobe.ne.jp/~gin/rock/japan/hanatarasi/hanatarashi2/hanatarashi2.html. With Yamatsuka Eye (Boredoms, Naked City) on voice and, well, bulldozer. (Thanks Maarten for the link).

Btw: the bulldozer was stolen, the owner of the venue did not know about it, and the entrance of the venue was destroyed: the bulldozer crashed right through it.
