A double album (or double record) is an audio album which spans two units of the primary medium in which it is sold, typically records and compact disc. A double album is usually, though not always, released as such because the recording is longer than the capacity of the medium. Recording artists often think of double albums as being a single piece artistically; however, there are exceptions such as John Lennon's "Some Time in New York City" (which consisted of one studio record and one live album packaged together) and OutKast's "Speakerboxxx/The Love Below" (effectively two solo albums, one by each member of the duo).
