This collection of 150 photographs by Swiss photographer Balthasar Burkhard (b. 1944) documents the legendary exhibition Live in Your Head: When Attitudes Become Form (Works, Concepts, Processes, Situations, Information), organized by curator Harald Szeemann (1933–2005).

Presented at the Kunsthalle Bern in Switzerland from March 22 to April 27, 1969, Live in Your Head was a sprawling and controversial international survey of postminimalism and arte povera at a moment when these movements had yet to gain wide exposure. Among the many participating artists were Richard Artschwager, Joseph Beuys, Walter De Maria, Michael Heizer, Eva Hesse, Alain Jacquet, Bruce Nauman, Richard Serra, and Lawrence Weiner.

This digital collection forms part of the Harald Szeemann Archive and Library.
