Cockatiel is the first official album produced by vocarock producer il cremonese (okame-P) after a series of long run being active in the vocaloid community, already producing several music for an unspecified number of years before the release of this album which came out on April 10, 2013. It is also dedicated to the producer's deceased pet. Only containing 12 songs, this album has the least amount of track in il cremonese's album so far (discounting the sanctuary EP which isn't an full feature album), with a unique property being the inclusion of IA's vocal in the last track, which was rarely used by him.
