Jason Simon's research-heavy paean to the historical significance of video art is reflective without being sentimental. It's easy to get lost in a single black binder, a facsimile of a catalogue of films and videos for sale or rent produced by the Castelli-Sonnabend galleries in the mid-1970s. (Back then, work by Acconci, Nauman and Jonas et al. ranged from $25 to rent to $1,000 to buy.) There's also a TV playing Video Against AIDS tapes, a glass installation (made with Josiah McElheny) based on video projection booth windows, and stainless steel wire sculptures made of balled-up sound recordings.
