Nina Gordon (Veruca Salt) Covers NWA

Here are the lyrics, in case you'd like to sing along:
Straight outta Compton crazy motherfucker named Ice Cube
From the gang called Niggaz With Attitude
When I'm called off I got a sawed off
Squeeze the trigger and bodies are hauled off
You too boy if ya fuck with me
The police are gonna hafta come and get me
Off yo ass that's how I'm goin out
For the punk motherfuckers that's showin out
Niggaz start to mumble, they wanna rumble
Mix em and cook em in a pot like gumbo
Goin off on a motherfucker like that
with a gat that's pointed at yo ass
So give it up smooth
Ain't no tellin when I'm down for a jack move
Here's a murder rap to keep you dancin
with a crime record like Charles Manson
AK-47 is the tool
Don't make me act the motherfuckin fool
Me you can go toe to toe, no maybe
I'm knockin niggaz out tha box, daily
yo weekly, monthly and yearly
until them dumb motherfuckers see clearly
that I'm down with the capital C-P-T
Boy you can't fuck with me
So when I'm in your neighborhood, you better duck
Because Ice Cube is crazy as fuck
As I leave, believe I'm stompin
but when I come back, boy, I'm comin straight outta Compton

Nerdcore Rising - the Trailer

"Nerdcore" is a pretty self-explanatory name for a new-ish type of hip-hop that combines beats with social awkwardness. From the site:

Hilariously entertaining, NERDCORE RISING introduces a new wave of hip-hop to the world called “Nerdcore” where computer obsessed geeks bust rhymes about the hard knock life of nerdom. The gut-busting comedy follows MC Frontalot the “Godfather of Nerdcore” on his first national tour where the roots of the genre, the dorky complexities of its artists, and one MC’s fight for nerd stardom is revealed.

Mad Villain - All Caps

MF DOOM and Madlib are Madvillain. The two met in 2002 and soon began working on Madvillainy which would be finished over the next year and released in March 2004. The music on Madvillainy went against the grain of all popular conventions in contemporary hip-hop: short songs, dirty sound, no choruses, and with lyrical themes which were not always clear to everyone on first listen. The album received the highest critical praise of a hip-hop album released in 2004, and years later has continued to generate interest and controversy.

The main character in the video looks like a mixture of Rorschach from Watchmen and Dr. Doom, which may not be a coincidence, since one of the Emcees is named MF Doom. I tend to be sort of a hip hop snob, since I listen to that which is considered underground, but take my word for it when I say that MadVillain is Hip Hop on the highest level. 'All Caps' comes from the album 'MadVillainy', and you can buy it on Amazon.
