The music band 'Lifehouse', made a video called 'Spin'.  I am trying
to find out how what 3D archtiectual Animation company they used to
create the animation of the city spinning.  This is shown twice in the
whole video.  very impresive.

thanks

The version of the video that I've seen has a "Dreamworks Universal"
credit on it. Dreamworks has a CGI animation studio. However, I'm not
sure that the spinning city involves CGI animation. Although I've only
seen a rather low-res video, it looked to me as if this was simply
aerial footage. A plane or helicopter circumnavigated downtown Los
Angeles while shooting film or video, and the footage was later sped
up.

Here are some credits for the video:
