Apparently, there is a metal band that goes by the name Akira Kurosawa. Hailing from Victoria, Australia, they have a MySpace page with three songs and two YouTube live videos (Deus Ex Machina, How to Stop and Exploding Man), which is how I found out about them.
It is not quite my type of music, but perhaps someone here is able to appreciate Akira Kurosawa, the band. If so, let me know what the actual connection between the band and the director is.
To call that music is a bit of a stretch. The name choice is a bit confusing, and the lyrics show no connection, its just typical all hope is loss type stuff. At any rate the name choice is just stupid no matter what.
