Allora and Calzadilla Art 21 link

Here is the link for the Allora and Calzadilla interview on Art 21. All of their videos are on this site. Also check out their lecture with the Renaissance Society at the University of Chicago. As for Lida Abdul, here's her website, but again, just film stills and photographs, no actual videos are here. If interested, just Google her name and click the videos tab. Snips, picks and talks will pop up which are all interesting.
