The cool thing about Tori Amos is you don't need backstage passes for Tori. If you show up several hours before the show (try to check local fan clubs for exact details of time and place) Tori always does a "meet and greet" at the stage entrance. She sometimes only signs one item per person so bring the item you most want signed, however on occasion has been known to sign more than one item. Tori is also very nice in person!
One fan reported:
I've met her twice just showing up and when you see a bunch of people gathering by a doorway go there. I have never had any trouble meeting and talking with her. Tori is awesome!
