Vanity label: A vanity label (see related topic on vanity press) is an informal name given sometimes to a record label founded as a wholly or partially owned subsidiary of another, larger and better established (at least at the time of the vanity label's founding) record label, where the subsidiary label is (at least nominally) controlled by a successful recording artist, designed to allow this artist to release music by other artists they admire.  The parent label handles the production and distribution and funding of the vanity label, but the album is usually released with the vanity label brand name prominent.  Usually, the artist/head of the vanity label is signed to the parent label, and this artist's own recordings will be released under the vanity label's brand name.  Creating a vanity label can be an attractive idea for the parent label primarily as a "perk" to keep a successful artist on the label's roster happy and a venue to bring fellow artists to the public's attention.
