DZ is best-known as a Famitracker/OpenMPT musician who probably has more YouTube clout than the rest of us on VGF combined. They are among the very few people in the universe to have covered songs from both Ristar and Maniac Mansion. In terms of visual art, their thumbnail game is strong, and they also do sprite work they post on DeviantArt (see samples below). Important note: they write absolutely bangin' song covers, but don't sleep on their original work... "Leaves on the Sidewalk" (embedded above) is an iconic rainy-day autumn weather piece.
