Hey, the LOTR at the social was Muldoon's suggestion. Here's the breakdown of nerdcore, don't have to bother with WinMX for most of it.
MC 900 FT Jesus - Precursor to Nerdcore. Ask SE about it, but it's commercial music, and very good.
Del the funky homosapian/ Deltron 3030 - I think the first commercial nerdcore artist. I've only heard one track, but it owned. It was called Proto- CUlture, and I could go into a page long breakdown, but suffice to say it's about Video Game cred.
MC Frontalot - The guy who invented the genre. All available free over at
www.frontalot.com. My favourite, witty lyrics, and a slowish, cautious rapping style.
MC Hawking - Rapping Stephen Hawking! Available for free at
www.mchawing.com, but he's currently working on releasing a CD.
Lords of The Rhymes - available free at
www.lordsoftherhymes.com. You already know the deal, they rap about LOTR.
MC Chris - at
www.mcchris.com you can download some tracks, and buy some cds. Ultra fast, super skileld rap, unique because of his high pitched voice, but it works. He raps about some fairly explicet stuff though.
MC Paul Barman - only a few free tracks at his website, for the rest, buy the disc. Hyper-intelligent rhymes about stuff like Politics and stuff. Be warned, he has tracks so rude (but intelligent) that make MC Chris look like a pansy.
The Frontalittle Squad - An group of internet nerdcore artists, 2nd generation, who rap about really nerdy stuff like video games. Some of my favourite stuff, available at
http://frontalittle.songhole.org.
Double A Ron - Some of his stuff is at
www.vgmix.com. I really really like his stuff so far. He's a christian rapper who raps over video game music remixes.
Assorted - a bunch of other ametuer rappers do nerdcore at
www.vgmix.com. Also check out DJ Crono, who has stuff at
www.ocremix.org.
