I would much rather invest in a deadmau5 concert than Skrillex because I've never been to one of Mau5' concerts, but I've watched his shows from my laptop when he goes live at Ultra and other venues and he is definitely a must-see. From what many fans of the horde say, he goes nuts when he's unhooked and he does come to SF on a fairly regular basis. I missed him last fall but I would love to go see him and I think it would be a wise choice to invest in him when he comes to SF
