Artist Sean Kealy, who posts videos to YouTube as kealytronart, has put up a clip of him drawing Machine Head frontman Robb Flynn. The video compresses approximately four hours of drawing time into six minutes, and Kealy says a friend of his was running sound at Machine Head‘s Dublin concert, and showed the drawing to Robb, who signed it for him!
