The cDc stands for the Cult of the Dead Cow, a play off of Center for Disease Control. They are a hacker group from the 80s and 90s, who also make pretty interesting music. They have a whole collection of songs, but these two are my favorites.

Fried Chikken - A song of fried chicken

Evil Clown - A boy gets a clown for Christmas, and it's pretty evil

Heres the whole set of their music if you enjoy it.
