In opus mors, the Danish sound artist Jacob Kirkegaard cautiously approaches the conclusion of life: death. Kirkegaard describes four sonic environments in which the human body usually finds itself postmortem: a morgue, an autopsy, a cremation, and the process of decay. The sound occurrences connected to them, which one will never be able to sense with one’s own body, are hidden in a twofold sense. On the one hand, these environments are not accessible to the public. On the other hand, explicit knowledge of what happens to the body after death is a frequently avoided and/or taboo subject. Kirkegaard’s work is a haunting and intimate sound meditation that puts us in these four spaces of death.
