For the 4th year, dancers from Avant Dance and Event Center will infect Monument Square with awesome choreography, absolutely gruesome make-up and costumes. 

When we get out work tonight, dozens of zombies will be bustin' out sick moves recreating Michael Jackson's historic 1983 video. It's the annual Thriller Throwdown back again to get us in the spirit of Halloween! The thrillah chillah flash mob strikes fear into the heart of Portland today at 5:30.
