Let's face it, a lot of us like Metal. Sure, some of us don't admit it, and I never considered myself a diehard metal fan, but we do, be it Metallica or Maiden or Slayer or all of those. Anywho, here's some metal albums I've been enjoying so far, in no particular order.
Agalloch-Ashes Against the Grain-This is actually pretty awesome. It's black metal (never cared for most of it-or at least the Norweigen stuff) but it's great. It could best be described as Gorgoroth (without the cliche satanism) meets Katatonia meets Sigur Ros meets Pink Floyd meets My Bloody Valentine.
Mastodon-Leviathan and Blood Mountain-Holy shit, the drumming. If you claim to enjoy metal but don't like Mastodon, then you don't really enjoy metal. Seriously, give them a shot, they are fucking awesome. Hell, they let guys from the Mars Volta on Mountain, and they didn't ruin it. That's saying something.
Slayer-Reign in Blood-Need I say more?
Athiest-Unquestionable Prescence and Elements-Death Metal with jazz-inspired chord progressions. Not the only Death Metal band to do this, but one of the few to do it right. See also: Cynic's Focus, Gorgut's Obscura, and Pestilence's Spheres.
Sleep-Dopesmoker and Sleep's Holy Mountain-The Ultimate Stoner Metal albums, with riffs that are so sludgey, they roll like molasses. See also: Electric Wizard's Dopethrone.
Boris-Rainbow, Pink, and Amplifier Worship-Hell yes. The best Doom Metal band on the planet, and one of my favorite bands that are more recent. Rainbow is more psychedelic rock than metal, but it's still great.
Wolves in the Throne Room-Diadem of 12 Stars-Black metal that's really long (4 songs, a 60 minute album), but every minute counts. Contains elements of folk music, and bit of post rock.
Nachtmystium-Instinct: Decay-While it has the cliched low-fi production that annoys me, here's a Black Metal album that's still worth it. Featuring elements of psychedelia and post punk, it's pretty diverse. Oh, and the song "Chosen By No One" rules.
Sigh-Imaginary Sonicscape-Black Metal from Japan that's awesome. Sure, it's Black Metal, and it has the symphonic cliches, but it also has elements of psychedelia, electro, dub, jazz, and reggae. It's like Mr. Bungle if they did a Black Metal album, and it rules.
