This is one of my favourite nerdcore tracks: Optimus Rhyme - Obey the Moderator

Agreed on Wu-Tang, I didn’t like them the first few times I heard them and dismissed them as gangsta rap, but they aren’t really. They can be pretty hardcore with their language and do have a lot of gang-related themes, but RZA’s spooky hypnotic beats mixed with classical music are phenomenal. Sometimes their rhymes seem to make no sense but are just combinations of words that sound great together, and the samples from old kung-fu movies complete their unique sound. So many guys that can flow in that outfit. RIP ODB!
