What's wigger slam?
Slam metal is just death metal that focuses on the mosh parts instead of the thrash parts. It's very straightforward. They key elements are a very ringy snare, guttural cricket vocals, and of course tons of slam riffs. Wigger slam metal is simple slam metal played by wiggers. And there is no shortage of this stuff, as you will see.
The early years: Long Island guido slam metal
In the beginning, there was Internal Bleeding. And before that, there was Pyrexia and Suffocation. But it wasn't until Internal Bleeding that the guido and wigger elements crept into the slam sound. They had lots of slam riffs and acted like tough guys. It makes a lot of sense when you think about how stupid people from Long Island are.
Then you had bands like Repudilation and Entorturement that took it to the next level of wiggerdom by actually rapping over slam riffs. It was equal parts totally ridiculous and totally fucking awesome. I still listen to the Repudilation demo all the time. Rounding out this scene were bands like Dehumanized and Disfigured that slammed like crazy but lacked the wigger overtones. They're still worth listening to, though, even though you'll miss the wig.
The next generation: Devourment and Texas slam metal
However, it was really Devourment that created the genre we know today as wigger slam metal (although they were mostly Mexicans... but whatever). They introduced some of the common elements such as TR-808 bass drops, gravity blasts, and post-Internal Bleeding cricket vocals. I mean Frank Rini had some deep-ass vocals but in a totally different way from Devourment. Most wigger slam bands these days are essentially just refining the Devourment formula, ever so slightly improving on it every time. It's almost as though Devourment was put through the Toyota kaizen process a thousand times, getting a little more refined each time. I think Jack Welch would be proud. Other notable bands of this generation include Sect of Execration, Prophecy (keepin' it fuckin sick!), and a zillion other bands I can't think of right now. Viral Load or something I guess.
The new wave: Wigger slam goes international
New school wigger slam metal just might be my favorite kind of music in the whole world. These days most of the wigger slam metal happens in places like Russia, Japan, and Scandanavia. I think this is because their malformed third world minds don't quite understand how absurd and uniquely American it is to wear camo shorts, basketball jerseys and play slam riffs with cricket vocals. But whatever, because those Japanese really know how to fuckin slam, I'll tell you what. The Russians are developing a really distinctive style as well. But the Americans are still holding it down. You definitely need to check out Cephalotripsy- they sound just like Voracious Contempt but with even more machine-like slams, an even ringier snare sound, and even deeper vocals.

Here is a song by Rest In Gore that's maybe the very best example of the latest wigger slam stylings from Japan.
And here is a video by the Japanese wigger slam metal band Glossectomy. Please note the MC Hammer-like beanies and wiggerish arm movements.
Budget Wigger Slam
There is a small but important sub-genre of combines the lo-fi production and sloppiness of grindcore with the traditional wigger slam style. We call this budget wigger slam, and it is typically found in the wilds of MySpace. There are zillions of these bands, and like noisecore, you either like all of them or none of them. I like lots of these bands, with Artery Eruption and Grymer being excellent examples. But fucking Malignant Rupture are the kings of budget wigger slam! They're like 15 years old and slam like there is no tomorrow. I hope they put out a demo or something, I can't stop listening to their MySpace song.
Big Chocolate
This 17 year old kid, who goes by Big Chocolate on the interweb, really deserves his own entry in the annals of slam history. In my opinion he is the finest wigger slam metal musician in the history of the genre, and I'm not even fucking kidding a tiny bit. I'm totally on this kid's balls. He is in the bands Disfiguring the Goddess and Malodorous. Please note his Wu-Tang shirt.
