I love this thread! I have missed out on many of these albums, so thanks! You all seem to have great taste in music, so I find myself upvoting almost every comment. You have mentioned almost all of my favourites (e.g. "Nevermind", "OK Computer", "High Violet", "Yankee Hotel Foxtrot", "Lateralus", "Loveless", "Good News For People Who Love Bad News", "The Suburbs"), although this list needs:

• Jimmy Eat World - Clarity Example A fantastic album that I find perfect for almost any occasion. I honestly can't find a better replacement for this one, so it just sticks with me.

• Alice in Chains - Dirt Example Every AiC album is just outstanding, but if I had to pick one, it'll always be Dirt. It might just be because I've listened to Dirt a lot more than the others, but I'll try to be more down-to-earth in the future.

• Failure - Fantastic Planet Example A highly underrated album and, in my opinion, one of the best of the 90's.

• Deftones - White Pony Example Really just another amazing album by Deftones.

• Bombay Bicycle Club - A Different Kind of Fix Example An album I didn't like too much at first, to be honest. It's atmosphere really grew on me though. It really deserves a spot here now.

• Megadeth - Rust in Peace Example Might just be the best thrash metal album of all time.

• Sonic Youth - Daydream Nation Example There is not really a lot to compare this album to. Few albums have had such an influence on the alternative rock genre.

• Slowdive - Souvlaki Example Souvlaki has some of my favourite songs of all time. It's such a shame it's so underrated and looked past.

• Porcupine Tree - Fear of a Blank Planet Example Just a great concept album. While older progressive rock can sometimes feel just a bit... dated to me (excuse my ignorance), this album feels to me like a more modern approach from a classic prog-rock band.

• Pain of Salvation - Remedy Lane Example This is a masterpiece plain and simple. Another thematic prog-rock album. It is very hard to experience in it's full glory without listening to it from start to finish.
