I would be very concerned and frightened. Mostly because Jimi Hendrix has been death for a long time.
If you mean the lead singer of the last concert you've been to, then I would feel a mix between grossed out and happy. On the one hand I'm really not attracted to older men with a beard, on the other hand I would most likely be in America (Either he would have to be teleported to me, or I to him. And since his mass is larger I find it more logical to assume I would be teleported to him). And I like being in America (wouldn't want to settle down there though).
