But, yeah... never ever get a pixel heart tattoo unless you want to get made fun of really badly. That is honestly the worst fucking tattoo I can think of right now. Ick.
Perhaps off topic, but does any one know if there's a collection of Alberto Gonzalez songs out there for his NES soundtracks? I know there was a big .gbs file out there for all his Game Boy soundtracks.
Clear one of your tracks and play the part live with your midi controller. Otherwise, if it's got knobs n shiz, link it to some effects to do live. Kids go crazy for slow cutoff fade-ins.
One of the more obvious answers would be Disasterpeace, but previously mentioned Norrin Radd and Virt are both fucking sweet. You might like Animal Style as well, he uses heavily distorted guitar (sounds like 8-bit fuzz) to go along with his music. My suggestion would be to browse through the catalog at iimusic.net, I'm sure a lot of it will cater to your taste. Perhaps not like prog metal, but Plain Flavored's music is definitely progressive in some variation of the term and also rather technical/ experimental.
