Lizzie Fitch and Ryan Trecartin, still from “Ready,” 2010. (Image courtesy of the artists) With frenetic editing, absurdist humor and a stubbornly improvisational ethos, artists Lizzie Fitch and Ryan Trecartin create deliriously non-narrative videos, sculptures and installations that both investigate and embody the arch, hyper-self-consciousness of social media and reality television. On Feb. 4, Fitch and Trecartin will discuss their collaborative practice as part of the spring Public Lecture Series, sponsored by the Sam Fox School of Design & Visual Arts at Washington University in St. Louis. In all, the series will feature 22 virtual presentations by renowned artists, architects, designers and scholars. Archival slides of the Charles E. Fleming House, Town and Country, Mo.
