You can't help but be a fan of the 70s stuff.
You can't help but Barf into a Bucket after listening to the 90s and beyond stuff.
Fun? Overrated concept.
I would agree that 90's and beyond does not compare. I can find some enjoyment in their later stuff but man, the early stuff is where it's at. I'm sure you can say that about almost any band that has been around for so long though.
