Their first 3 albums, I still listen to from time to time, but the last 3...not so much. I thought Ill Communication was very spotty, in that what was great was great and what was bad, well, I actually don't remember it. Must have been that traumatic. Others did seem to like that one a lot, though. Hello Nasty starts off nicely, but dies a little more than halfway through. The last album doesn't even go that far...
But License To Ill (childish as it is), Paul's Boutique, and Check Your Head have strong enough material to validate the niche these guys once had.
