This event at the Moore looks promising for the early end of Halloween, 2009:

A massive collaboration from Degenerate Art Ensemble that is part dance spectacle and part concert, a little bit punk-rock and a little bit Butoh. Featuring musicians Joshua Kohl and Jeffrey Huston, dancers Haruko Nishimura, Trinidad Martinez (Pat Graney Company), and Marissa Niederhauser (Maureen Whiting Company), set designer (and Stranger Genius) Jennifer Zeyl, video by Leo Mayberry, and many, many more. Sonic Tales should float by like a dreamy, postmodern fairy tale.

For the late end: Rumor has it Orkestar Zirkonium will assemble at Cal Anderson Park around 11 to march around and inflict their delightful Balkan brass-band havoc on the Halloween drunks.
