Solitary confinement, colloquially referred to as "the hole" or "the pound" (or in British English "the block"), is a punishment or special form of imprisonment in which a prisoner is denied contact with any other persons, excluding members of prison staff. Usually cited as an additional measure of protection (of society) from the criminal, it has also been called a form of torture. In some cases it is also used to protect the prisoner himself.

Solitary Confinement is a 1992 album by Leæther Strip and released by Zoth Ommog Records, which continues the heavy electro-industrial style of Science for the Satanic Citizen. As is usually the case, it incorporates a number of voice samples, for instance from the film A Boy and His Dog.
