Audiovisual Aerial Performance

I have a (partial) video of this act while they were performing for the opening ceremonies of this conference I attended back in 2011 in Amsterdam. Then I saw this opening act for a TEDx conference (TEDx Brainport) in the Netherlands just this year. It's apparently the same group. The TEDx organizers call it an audiovisual aerial performance. Complete with live music (at least for last year's performance). Interesting. Check it out.
