Which Music Artist is a Must See in Concert? [Poll]

Imagine this scenario...you've just woken up from being in a coma for five years and you get a chance to go to any concert you want.  What music artist is the first one you want to see in concert? You can enter your answer below but you should know that this event actually happened back on May 7, 2011, when 79 year old, Evie Branan, of Michigan, woke up without notice from her five year coma.  Her very first words were quite a surprise too.  She said, "I want to go to a Bob Seger concert." Evie will get to do exactly that.  Tonight she will be joined by two nursing home workers who cared for her when she was in her coma, and all will see Bob Seger in concert, in Auburn Hills, Michigan. Not only that, but she gets to meet Bob Seger and says she plans on giving him a big smooch.  Lucky Bob!

Now tell us who you would want to see after waking up from a coma. I would like to see Madonna since I've already seen every music artist I really want to see.
