Here's a 2001 interview (http://www.donshewey.com/theater_articles/jessica_hagedorn.html) with Hagedorn where she talks about the book, including the name. Um, vague spoilers?

But -- she's friends with Ntozake Shange & Thulani Davis! She's collaborated with Shu Lea Cheang (whose name was misspelled -- in two ways -- in the interview article)! So -- definitely yes to smart and critical!
