When Doug Aitken’s “Migrations” was first screened at the Carnegie International 2008, I missed it. This was a mistake. In fact, it should have been easy to see. It was projected each evening in massive format on the front of the museum’s rectangular facade. Now part of the museum’s modern collection, the Aitken film is housed in a small theater, with a long narrow bench that fits no more than a half dozen viewers at any time. This is where I became engrossed by the film. I’ve looked for it online many times, but have never found footage. Until now. Here’s a nice teaser. Though seeing the film in-person and in its entirety is highly recommended.
