Amos will kick off nearly three months of shows October 9 at the Palace Theatre in Albany, N.Y. Venues and cities announced so far include a pair of dates at the Theatre at Madison Square Garden in New York City (October 11-12), the Orpheum Theatre in Boston (October 18), Hummingbird Centre in Toronto, O.N. (October 23), and the Fox Theatre in Detroit (October 27).

While dates and cities for shows in November and December have been announced, bringing the total to almost 50, venues for those shows have not been finalized yet.

Cities on the list include Indianapolis, Chicago, Nashville, Atlanta, Dallas, Austin, Denver, Salt Lake City, Seattle, San Francisco and Los Angeles.

Posse, which is Amos’ ninth album, introduces the world to the five distinct characters – Isabel, Clyde, Pip, Santa and Tori – the singer said combine to make a complete whole.

She said that while looking back at her work, she realized each personality has surfaced in the past, which accounts for previous albums tackling a single theme.

“I was exploring one personality at a time,” Amos said. “So if you look at all the records, I was exploring these character traits, these feminine personality traits, usually in a sonic narrative form. And together they make the complete woman.”

Amos said this revelation has allowed her to put the pieces together for the first time.

“For many years I have been an image that isn’t necessarily who I am completely,” she said. “I have made certain choices and that doesn’t mean that those choices are the whole story. I think that these women are showing me that I have not explored honest extensions of the self who are now as real as the redhead.”

Each character has her own blog on Amos’ web site, and will make appearances on stage, complete with her own look, on tour.

“You’ll get to know the girls through the photographs, through the songs, and there needs to be writings,” she said. “Their relationships get more complicated. I love the idea of this multimedia project being improvisational.

“Improv in front of a mass audience…this allows the five women to explore and develop as opposed to them being restrained and contained in a portraiture medium. This way they learn and grow in front of everybody’s eyes.”
