Gorillaz is pretty bad... It sound exactly like what it is, that kat from Blur, with Del rappin. They sould call it "Blur the Funky Gorillaz". It's not terrible, but I don't see how Del could be considered "Underground". "Not popular" is more like it. Don't get me wrong, I like Del too, but underground? Bah.
And MasZive, you don't like East Coast underground because they use words that are too big? That speaks a million words for West Coast rap. Basically you're like "West Coast rap is more... dumb". Canibus is great. He can rip you inside out using 4 syllable words every time, and manage not to curse through a 5 minute song.
