Photography Jam Session?

How do we have a photographic jam session? I am not ready tonight to brainstorm this. But, I just saw this incredible video on Vimeo (through the blog at http://www.holidaymatineee.com).

Yours Truly Presents: The Morning Benders "Excuses" from Yours Truly on Vimeo.

It's amazing to see the collective energy going on here as a buch of friends jam and produce a killer sound. How do we do this with cameras? I want to know. Drop me a line below.
