"Eyes of the Insane" seems to start with an eerie Seasons in the Abyss vibe, then goes to some Slipknot style groove riffs done in a Slayer vein, then it continues to become even more hilarious.
"Jihad" does have some half-assed South of Heaven style stuff in there, but I don't really like the "yea yea yea yea yea yea" vocals, it sounds like he is trying to sing for No Doubt. Listen to the rapcore part at about 1:55.
