Manhattan in Motion by Josh Owens
Looks like it's time-lapse week for me. Last night, I stumbled upon this beautifully edited time-lapse video by Josh Owens aka Mindrelic. Shot from several hotel rooftops (you can find the full list of hotels here), Owens "spent a little over a month hotel hopping in Manhattan (March 12th to April 29th) shooting time lapse, these clips were pulled from over an hours worth of footage."
As for the music, it's called Lights Dim, from a New York based band called The American Dollar. (You can download a free compilation of 9 of their best tracks here.
