Not Available is the second studio album (released as the fourth) by The Residents. It was originally recorded as a follow-up to 1974's Meet the Residents. However, following the Theory of Obscurity, it was immediately locked away in a bank vault with no plans to issue it until the members of the band had completely forgotten about its existence. It did surface in 1978 due to continued delays on the Eskimo album and the Cryptic Corporation's desire to have some sort of Residents release, as the re-release of the single "Satisfaction" the same year had garnered some attention in Europe. The album itself is a dense concept album featuring a more musical and cohesive approach than that found on most Residents albums from the 1970s.
