An event is an occurrence....the fact or case that something happens, after which nothing will ever be the same again…. [it] disrupts any pre-existing referential frame within which it might be represented or understood …[it] is the radical singularity of happening, the ‘it happens’ as distinct from the sense of ‘what is happening’.

Following the event all that is left is a trace, an after-image, an anterior marker of a ‘something’ that has happened elsewhere, in another time/space. If we are to know anything of the (specific) event at all (‘outside’ of itself) it is as anamnesis, then the question becomes a matter of matter; of how this reclamation in-forms, or is to be formed.
