i can't answer this question but i'm also curious to know. his videos were cool, and he came across as a funny and cool kind of guy. i couldn't find his artist page either and i was sure he had one. where are u derrick?!
I just checked Derrick Pope's YouTube Channel and it says he logged in one month ago. So it looks like he is alive and well. I would recommend sending him a message via YouTube if his email address doesn't work.
