Reminds me of the good ol' days.
I was rigging old car parts and basically made a go-cart out of pieces of shit rust nothings. It took us well over 3 months to get it done but hell it was turned into a pile o rusty crap to a shiny, spiky, smooth looking demon of a go-cart. I wish we were listening to this while we were doing the welding, polishing and wiring.
I love how this song just makes you want to do something 'evil' in a sense of the word. And hell its even better if your experimenting on innocent little animals and infusing their DNA to make their stomachs produce sulfuric acid and attach little electric fuses on the wall of the stomach. H eh burn baby burn!
Anyways the bass is freaking awesome. I think to make it really evil you could add something with more of an industrial sound such as what was going on at 0:36. Anyways this is pure evil and not much more could be done accept if you accentuate the the high pitched intervals to flow more when the beat gets lower. Last word are; great job, great beat, great them = great song.
