Re: Meant to say that the last 3 albums on my list were disappointing
I think comparison to Raincoats/Essential Logic are misleading for Young Marble Giants - they're closer to something like the style of Kraftwerk or Suicide crossed with the pop brevity Guided By Voices. The muted ambience (sure, you can call it "dull") is a lot of the point. You could imagine a lot of the songs working okay in conventional rock arrangements, but the more sparse and cursory style gives them more immediacy.
I never got into Belly but I like "Slow Dog".
