It was an eye opener for me: Challenger. The album does what it's title suggests, it challenges. As soon as I got it, I turned it on and listened to it on the way back home. The ride on a ferry, in combination with the Mezzo Forte track, became one of my most precious music memories.
And I want to recommend you guys this. Because it's brilliant experimental music, with touches of solid noise. Look it up. Listen to it. I'm curious if you guys experience the same.
It's thus more a shame that the rest of his work sounds like a bunch of uninteresting meatgrinders.
