Post your lists! As a music junkie, I love checking out lists like these! Feel free to post reasonings as well if you're feeling it.
My personal list:
10. My Bloody Valentine - Loveless
So who's up for some shoegaze?! Anyone?
When most people hear the phrase, "My Bloody Valentine," they think of that horrible horror flick that has some guy in a gas mask chopping people up. That movie was stupid. This band is not. This album is unlike anything most people have ever heard before, I'd venture to say. It can only really described as a cacophonic blend of noises and brilliance that culminates into a beautiful journey. You're not going to understand much of what you hear, but you're just going to know that it's right. The lack of coherency yet beautiful culmination of the droning noises makes this a simply hauntingly beautiful work that must be experienced to truly understand. But it's definitely not for everybody, let's just get that out of the way now.
9. The Mars Volta - Frances the Mute
Well, here's another work that's more or less incoherent but in a different way. Once upon a time, this guy named Omar and his buddy named Cedric decided that they're way too good at music to make simple music like what they did with At the Drive-In. So they decided, "fuck it. We're gonna make one of the most ridiculous albums ever in terms of technicality and it's gonna melt your damn face." And that's what they did. And that's what Frances the Mute is. These are wickedly talented musicians that decided to be as crazy as possible, and it works so well. This album here contains only five songs and will last you more than seventy minutes, and they try to tell a story the whole time but no one really gives a fuck because the songs on this album take your brain and bend it backwards. If you can't tell, I like music to mindfuck me. This music does that.
8. The Beatles - Revolver
This album shits on Sgt. Pepper's face and kicks Abbey Road in the nuts. I'm serious. I've never understood the draw towards Sgt. Peppers. The Beatles made multiple superior albums in my mind, especially Revolver. I know this may seem like a boring ass choice, and that's probably because it is, but damn it Revolver is just a really good work by the most revolutionary musical group that has ever lived. These guys knew what the hell they were doing at this point, crafting masterpieces like Eleanor Rigby and For No One and not even caring. Their studliness is more or less unmatched on this record, as their true mastery of the art of songwriting is evident in almost every piece.
7. Radiohead - Kid A
I kind of wanted this to be a little higher, but I was worried people would call me a Radiohead fanboy douche or something, so I slipped this back to seven. But at this point every album is a masterpiece in it's own right so it's okay. Kid A is just a work of pure art. Thom Yorke's follow-up to the immensely lauded OK Computer did not disappoint in the slightest, and some even argue that Kid A is better. I'm not quite among that crowd, but this album is still pure magic to me. If you want to talk about an album that is utterly haunting in it's many complexities, here's the one to talk about. Radiohead ventures into a new frontier with this one, getting extremely experimental and pulling it off masterfully. There's not much more I can say about this that hasn't already been said though.
6. Arctic Monkeys - Whatever People Say I Am, That's What I'm Not
This album...is so fucking cool. Here's a rundown:
A group of British blokes gets popular online and releases this and it becomes the fastest selling debut album by a band ever. The album is a concept album that explores the actions of people in British night clubs.
Are you fucking serious?! That is just ridiculously cool, and the music backs it up well. The Arctic Monkeys are an awesomely band and absurdly underrated here in the states. WPSIA,TWIN is just an awesome ride of indie rock and post-punk revival (and by far the best album in that genre that I personally have ever discovered).
5. Neutral Milk Hotel - In the Aeroplane Over the Sea
If you consider yourself a big fan of Indie music...you know this album. It's just that simple. This is the definitive indie rock album, and probably the greatest that has ever been recorded if I'm being objective. This is a man that had a musical vision and he made it happen, and it defines the genre and is it at it's finest. This is a very simplistic album, yet one filled to the brim with such overwhelming emotion that you can't help but be utterly immersed from the first track to the last.
4. Modest Mouse - The Moon & Antarctica
The first three tracks of this album make up the greatest introduction to an album ever. Frankly, it may be the best string up three songs in a row of all time. Isaac Brock may be one of the most weirdly intelligent men on this planet. His lyrics are just so god damn introspective and clever. And don't even get me started on "The Stars are Projectors." That song is among the greatest of all time. I mean...A Day in the Life...Paranoid Android...Modest Mouse somehow ranks among those with that masterpiece. This album is definitely weird, but the experimentation and absolutely mind-numbingly good lyrics make it one of the greatest ever.
3. Arcade Fire - The Suburbs
If you haven't heard of this band, you're probably living under some sort of rock. They have received Grammys and overwhelming universal acclaim from critics and fans everywhere, and it makes me happy because they are EXTREMELY good. This is another concept album (I like those) that explores a theme throughout the entire record, and the name of it suggests what that theme is. Tracks such as "Modern Man," "Ready to Start," and "Suburban War" are so ridiculously well-written that you'll be exhausted by all the musicgasms you'll have by the end of the record.
2. Radiohead - OK Computer
If you don't already know a lot about this album...just Google it. I mean seriously. There is literally nothing I could say that hasn't already been said about this record. Every track (besides Fitter Happier and The Tourist imo) is a sheer masterpiece. This is when Thom Yorke decided, "fuck it. I'm too cool to be in a silly rock band. We are going to come up with some of the most brilliant pieces of music ever imagined." And that's basically what happened. Give this record a spin. You'll probably enjoy it.
1. The Antlers - Hospice
And this...is my favorite album. You have never heard emotion in music until you've heard this album. If you cry easily...you better be prepared with tissues if you want to emotionally invest yourself into what this album offers. I don't know to what extent this is autobiographical, but I really just want to give Peter Silberman a hug. This is another concept album that chronicles a dysfunctional relationship between a woman that is dying of cancer and a worker at a hospice. The lyrical and musical brilliance of this album is unmatched by any work I have ever personally heard. Do yourself a favor and give this record a shot. If you invest enough time into it, it will become more than just a work of music to you. It will become a chronicle of the nature of sadness and hopelessness in your life that you can turn to at any time.
