I prefer their debut over everything they have done since. Not necessarily in terms of the actual quality of the release but in that it always seems to be a slightly diminishing return in terms of excitement. Of course there are exceptions, and I always used to think track 3 of that debut album tended to be my fave song too but thats getting too hard to pin down.
This stems from a seperate thread about DJ Shadow's Endtroducing who is the perfect example of this. Perhaps I'm just too keen to move on to the next thing!
