Just an alternate view of how I see modern Quartz Quadrant theme. It turned out sounding close to Sonic Generations' mission themes, that explains the title.

Mixing this was really painful, I'm sorry if this has big problems in that terms. I hope it's still enjoyable enough.

Quartz Quadrant Modern (Mission Theme)

Sonho meu  te zamba

* You're a nerd, right?
* That is hilarious!
* I hate nerds more than I hate MAD Agents!
* My colleague Mike likes nerds though.
* Probably because he is one!
* What an asshole.
