Thanks to Gray, I'm listening to Hanatarash right now:
Once when I was young and foolish (which I still am of course), I got Pizzicato Five mixed up with some Japanese noise punk band:
- Pizzicato Five? Oh, you mean that Japanese noise punk band?
- Yeah, like, no.
I had heard them on the radio a few times, but somehow missed what they were called.
Edit:
Someone described the music of Hanatarash as therapeutic and, yeah, I can see it used as such, like a headcleaner.
