A video by the band OK Go for its song "A Million Ways" has become a sensation on the Internet, with over 500,000 downloads.
The video was filmed on location — in singer/guitarist Damian Kulash's backyard. In it, the band performs a complicated dance routine, synchronized to the last finger-point.
The band maintains the footage was not intended for public release — but still, the video has found a strong following.
Robert Siegel talks with Kulash and his sister Trish Sie, a former professional ballroom dancer who choreographed the dance.
