These guys rock, their Lord of the Rhymes is a nerdcore Hobbit/Middle Earth parody of Tolkien’s finest. Check out the music video (large, 40.5mb download), it is amazing. The other mp3s aren’t bad, but the video is clearly the best. Turn it up loud.
I came across this nerdcore stuff via a Slashdot posting “Nerdcore Rap In The Press”. Some of the mp3s stuff over at Optimus Rhyme are pretty cool as well, though more geeky. If you’re a True Geek (and not easily offended) then these lyrics will give you a taste of what it’s all about.
