A recorded performance preserves the result while changing what it means to be present.

Recording something changes what being there is worth. Once the result will exist afterwards, attending stops being about access to the music or the speech and becomes about the room, the risk, the fact that this particular night cannot be repeated. Presence turns into a different way of receiving a thing rather than the only way.

Decide before an event which of the two you came for. If you are in the room, consider watching rather than filming, since the recording will probably exist without your help. And when you cannot attend, take the recording seriously as its own thing.
