Yes, I can totally understand that. I never saw those bands that many times so I was never really disappointed. Kemialliset Ystävät were always good though. But yeah, there's a limit to what hippies banging broken toys thru loop pedal can take you.
I sort of lost my interest to that stuff many years ago. I just cant be fucked anymore.
One artist who sort of emerged from that scene that I've seen in the last few years is Pekko Käppi, who plays jouhikko, which is a bowed lyre from many many centuries ago. He was great when I saw him opening for The Ex.
