Even though she has 17 new songs on her new album, "Abnormally Attracted to Sin," Tori Amos promises she'll play plenty of familiar fare during her Sinful Attraction Tour, which begins July 10 in Seattle.

"I think a live shows has to be inclusive of your whole catalog -- that's how I look at them," Amos tells Billboard.com. "The new record always sets a tone, but the catalog will be there. By utilizing the whole catalog I think you're able to tell a different story every night.

"I just feel if you come to one of my shows, there are a lot of songs, and I think that each night can be different when you have a big catalog. Why not give different songs an opportunity to come out and play?"

Amos says variety will be paramount when she convenes rehearsals in a couple of weeks with drummer Matt Chamberlain and bassist Jon Evans. Even Amos' regular guitarist Mac Aladdin played on "Abnormally Attracted to Sin," but because the new album is so keyboard-driven she's decided to return to a trio format for the tour. So, she notes, "rearrangements will have to happen."

"There will be long days and long hours; everyone has to have their chops up for a lot of songs," Amos explains. "Once you've been playing for awhile, four weeks into a tour, your chops are tight and you know a lot more songs. But when you're starting you have to really build your repertoire back up -- and the light guys and sound guys, everybody's got to dial in and program their individual responsibilities.

"And when you're changing the show every night, that means you can't just sit back and do crack..."

Amos will spend a little over five weeks touring theaters in North America, followed by four U.K. shows in early September and a Sept. 17 date in Amsterdam.
