5 Opeth mentions and none of them are the awe-inspiring last 4 and a half minutes of "Blackwater Park"?
Other great ones:
The reason I was so disappointed with Traced In Air. Find a scientific way of quantifying the quality of music, some 50 years in the future, and then total Traced In Air. If that number is higher than "How Could I"'s number, I'll eat a Steinberger. :lol:
On the complete opposite end of the technical spectrum, here's Crowbar. This song is more than one-third outro breakdown. I'm a sucker for outro breakdowns, though, and when Kirk Windstein decides he's going to crush you with a riff, nobody with his hands intact does it better.
