I may be late to the game on this one, because Ronald Jenkees has over a million channel views, but Moodswung sent me a link to a song on YouTube, and at first, I thought it was a joke, some guy acting like an autistic spaz. Then he started playing music on his keyboard and I realized he MUST be autistic, or at least a serious music nerd with a gift of creative genius and serious keyboard skills.
And this one validated his skill level for me.
His YouTube intro is just great. The studio mixed teaser-length versions are linked on his blog here. Wow.
