NA meaning in Messaging ?

Answer:

What is Not Available mean?

Not Available is the second studio album (released as the fourth) by the Residents, recorded in 1974. The album was allegedly meant to only be released once its creators completely forgot about its existence (adhering to their "Theory of Obscurity," in which an artist's purest work is created without an audience) - however, due to ongoing delays in the release of Eskimo, Not Available was released to supply the demand for new Residents material, given their unexpected critical and commercial success following the release of the Duck Stab EP.

The album is considered by many to be the Residents' most masterful and beautiful work.
