I don't know, man; _that_ was pretty aggressive. You could try various tweaks (a doubling of or instrument in octaves with the bass, horn stabs, a vocal sample, the aforementioned vocal chant, a string and low brass part; something lower and 808-ish/hum-kick on the bass drum; an "aggressive" lead synth line)... Lots of options, but that was really agressive!
