Nerdcore should not be confused with bands that are simply stereotypically popular with nerds such as They Might Be Giants, DEVO, Ween, etc.
Musicians in this genre include (but are by no means limited to):
The Aquabats (definately moreso in their later albums)
The Phenomenauts (Mainly because of their pre-occupation with science)
MC Paul Barman
Del Tha Funkee Homosapian (specifically on the "Deltron 3030" album)
The Lords Of The Rhymes
The Laziest Men On Mars
oh and wouldn’t all of those tough rappers hate it
if the nerdcore rose up and got elevated?
we consider the possibleness of this not overstated."
-MC Frontalot, "Nerdcore Rising"
