best live singers and performers?

what artists

do you consider to have excellent live vocals?

and put on interesting and varied live shows?

i love it when there are different versions of songs played on the stage, or fused with other songs. hearing album versions is just boring imo.

Iron Maiden, Nine Inch Nails, Marilyn Manson and Cradle of Filth (By that, I mean that they sound the same live as they do on their studio albums).

Slipknot can't sing live, but they're still the best band ever (except for Iron Maiden and Slayer).
