I love yooooou. I have their entire discography, and I would honestly recommend getting them all. But, okay, since you started with With Teeth... What you have to understand is that each album is extremely diverse, and you have to have an open mind. I'll just describe each album here for you, and you can decide what suits your fancy. [quote][b]Pretty Hate Machine:[/b] This is where classics like Head Like a Hole and Terrible Lie are from. It's a highly synthed-up rock album, very industrial, very angsty themes. The highlights include the songs I mentioned earlier, and a lot of tracks have an air of "early installment weirdness", in that his voice is still young and a lot of the sound has aged (and very well, in my opinion). There is the token soft piano piece in Something I Can Never Have, a song that's close to my heart (I wish to play it at my father's funeral). A lot of the lyrics are angsty and there's a lot of break-up themes. Not sure if that's to your liking.[/quote][quote][b]Broken:[/b] This album was made after the label Trent signed onto at the time, TVT Records, was pushing pressure onto him into making another Pretty Hate Machine style album. Trent didn't like that. He wanted to make another album in a different style, completely different to that of PHM. So, in complete secret, he made this heavy metal-oriented album. It's very loud, very angry, and very metal indeed. The lyrics are abrasive and the sound is raw and in-your-face. It's also their shortest album that isn't a single.[/quote][quote][b]The Downward Spiral[/b] Considered NIN's magnum opus. A very dark album, it tells the tale of a man who rose up, subsequently loses it all, goes insane, and ultimately, commits suicide. A lot of depression and heroin abuse went into this album. It takes the metal route Broken took, made it a little quieter, but a lot more dirty and angsty. This is where Closer (the I-wanna-f­uck-you-like-an-animal song) came from, as well as the first appearance of Hurt, the song Trent claims is no longer his, in favor of Johnny Cash's amazing cover.[/quote][quote][b]The Fragile[/b] A double-album. Over twenty-songs in this concept album that is loosely connected to TDS. The songs are even more loose in their connection; I've yet to interpret much from it, myself. This is an album that you shouldn't listen to on just any random day. You have to have the openest of minds to enjoy it fully, and even if you dislike a song at first, it's the kind of album that you have to listen to a number of times before you can enjoy it as well as appreciate its message. You have likely heard a lot of their songs in movie trailers. Just Like You Imagined was used in the 300 trailer. We're in This Together was used in The Avengers trailer. The Wretched was used in the Hansel & Gretel: Witch Hunters trailer. The Day the World Went Away was used in the Terminator: Salvation trailer. The genre of this album is... Very difficult to describe. "Industrial rock" are the two words I'd choose, but it doesn't really do it justice. There are better options for a beginner listener, for lack of a better term.[/quote][quote][b]Year Zero:[/b] If With Teeth is your first album, Year Zero may be more to your speed. It's just like With Teeth, but with even more electronic noises. It's also a concept album about Trent's then-vision of the United States, and how the state of affairs would be in 2015. It comes with its own alternate reality game, even. The remix album, simply titled Year Zero Remixed (Y34RZ3R0R3M1X3D) is far superior, in my opinion, but I would listen to Year Zero first.[/quote][quote][b]Ghosts I-IV[/b] The only album I haven't listened to entirely yet. It's thirty-six instrumental tracks. This is where NIN got [i]extremely[/i] experimental. I'd only recommend it to hardcore NIN listeners. If you have seen The Social Network by David Fincher, scored by Trent Reznor himself, some tracks from this album were used in that film..[/quote][quote][b]The Slip:[/b] This album was distributed for free online as a "thank you" to the fans, and as an acknowledgement that people would just steal it online anyways (Reznor personally recommends that people pirate his music anyway). It's another rock/metal oriented album, akin to that of With Teeth and Year Zero, but I personally don't care for it too much. It has a few gems, like Lights in the Sky, a piano piece, but all in all, it wasn't their strongest one, in my opinion. I'd give it a shot, though. It [i]is[/i] free.[/quote]So, over all, I'd focus on giving The Downward Spiral, Broken, and Year Zero a listen. In addition to the songs I mentioned above for you to try out, I'd also recommend listening to [url=http://www.youtube.com/watch?v=TgwrxcO48N8]Came Back Haunted[/url], a cut off their upcoming album, Hesitation Marks. [i]Very[/i] good track. Comes out September 3. And with that, enjoy the music.
