For a deeper look into the IF/THEN methodology that underlies If/Then Installed and other related performance projects, please have a look at the DVD If/Then Dialogues, available through Hatje Cantz:

From the publisher’s website:
In his performances, (Siegal) consistently appropriates new combinations of video, electronic music, dance, and interactive compositional techniques. Based on the IF/THEN formula, Siegal’s system of choreography involves the dancers in the creative process in highly ambitious ways.
This DVD uses video and text excerpts to examine his approach to dance. It is unusual in the way that it interweaves experimental movement with online choreography for educational purposes. In this way, new, interdisciplinary, multimedia forms of collaboration are explored in depth.
