What are some good concerts that you would recommend?

I'd consider, if you like Taylor Swift, shes going on tour very soon and it's going to be really good. She's always very good in concert. I saw Jonas Brothers too, haha, three times. Ive seen demi lovato too. And, Miley cyrus three times. Im going to see Tswift in may. Eminem would probably be good, hes great.
