Is Memory is purely subjective?

This performance is the act of rearranging slides in a slide projector.

During three months I bought old family slides through a Ebay.com. I was collecting family memories from families I never met before. 

And I proceeded to rearrange those memories in a narrative, overlapping some slides, and also leaving most of them empty, blank.

Also exploring the sound of the slide projector as an activator of memories, it was amplified. Among many blanks, some collages are made at the time of performance, reordering the memories; evoking memories of those who watch, and mine; seeing memories as a rearranging of facts.

The performance includes a microphone extending the slide projector sound, a sound box.
