Conclusion The IfThenElse 2000 EACFLAC performance wasn’t just an experimental gig — it was an early manifesto for an approach that treats code as instrument, error as opportunity, and audiences as collaborators. For artists and technologists today, it remains a useful model: create systems that reveal their workings, make room for failure, and design interactions that transform spectators into co-creators.

On a rainy November evening in 2000, a small venue in a mid-sized city filled with an unlikely crowd: programmers in hoodies, experimental electronic musicians, net.art provocateurs, and curious locals who had picked up a flyer promising “live branching logic.” The advertised act, IfThenElse, had been making waves in underground tech-and-art scenes for years, but their “2000 EACFLAC” performance became something more than a concert — it became a cultural knot where software, performance, and participatory ritual braided together. This post reconstructs that night, unpacks what made the event distinctive, and considers why IfThenElse’s work still matters for artists and technologists today.
