Query: How do you follow up a masterpiece?

It was going to take a lot to follow up Psalm 9. I bought Psalm 9 and The Skull when they first came out. Psalm 9 was just jaw-droppingly unique. Definitely in the top 3 metal albums of the 80's. The crying guitars just pulled your guts out. Back then it was the heaviest thing I'd ever heard. I swore I'd never hear anything heavier. Of course the next year Celtic Frost came out with Morbid Tales, but that's another story. Anyway The Skull was a complete success. I didn't think they had any shot but they came very close to matching the brilliance of Psalm 9. Crushingly heavy (for the time) with the same feel, but the songs were unique and not copies of Psalm 9. If you liked Psalm 9 you'll like The Skull ... and probably Trouble's 1990 self-titled release. Those are the three best.
