A concept album is an album whose tracks hold a larger purpose or meaning collectively than they do individually. This is typically achieved through a single central narrative or theme, which can be instrumental, compositional, or lyrical. Sometimes the term is applied to albums considered to be of "uniform excellence" rather than an LP with an explicit musical or lyrical motif. There is no consensus among music critics as to the specific criteria for what a "concept album" is.

An album is a collection of audio recordings issued on a medium such as compact disc (CD), vinyl (record), audio tape, or digital. Albums of recorded sound were developed in the early 20th century as individual 78 rpm records collected in a bound book resembling a photo album; this format evolved after 1948 into single vinyl long-playing (LP) records played at 33+1⁄3 rpm.
Albums c. 2000 came on compact discs stored in jewel cases.
Early record albums from the first half of the 20th century resembled photo albums, being packaged in book form on multiple 78 rpm discs.
