I have to say that that album has got to be one of the weirdest things I've ever heard and I listen to Interpol.
Let's not kid ourselves into pretending that there's anything weird about Interpol. You think NMH is weird because you listen to Interpol.
While there are many noteworthy bands listed, I think I have to the conclusion that Hum was probably the best "90's" band if you can classify music as such. Hum beats all other 90's bands on just about every metric you can imagine: Raw talent, production quality, emotion, meaning, lyrics, thought... There's simply no match, and I consider Pearl Jam to my favorite band. While I think that Pearl Jam is an incredible band on all those same measures, Hum exceeds them in all but vocal talent. Both You'd Prefer an Astonaut, and Downward is Heavenward are monumental musical achievements that were well ahead of their time, and are timeless in their own right.
Soundgarden, Pearl Jam, and the Smashing Pumpkins do come in a close second in terms of musical quality.
I feel that In the Aeroplane Over the Sea is also an astonish musical achievement. It is pure brilliance, raw in emotion, produced wonderfully. It's beautiful and brutal, unique and unforced. It's references to WWII and Anne Frank are impeccably done and mirror Magnum's inner issues very well. Although I'd say this is a top five record of all time, NMH is not the best of the decade, as the majority of their work is very amateurish, has terrible production quality, and reminds me of Handful of Peter, the late years (See Family Guy.)
Nirvana, I really don't know why Nirvana even begins to enter the equation when you're talking about the best. Nirvana is good on many merits, but there are dozens of bands that came out of the 90's that crush them on every measure, to include the bands the gave rise to them.
Alice in Chains, while worthy, tends to fall short of a some of the other bands. To be certain, they were absolutely talented. But their early records were commercialized and contrived, their last record seemed forced in one singular particular direction. While Jar of Flies is indeed an absolute masterpiece, some of their other work and their inability to mature is major drawback when you compair them to Pearl Jam, Soundgarden, or the Smashing Pumpkins.
