A collection of recorded music tracks released as a single unit.
An album is a curated collection of songs or compositions released together, traditionally on vinyl, cassette, CD, or as a digital download and streaming release. The album format emerged in the late 1940s with the introduction of the long-playing (LP) record, which could hold roughly 20 minutes per side. Albums may be unified by theme, mood, narrative, or simply collect a period of an artist's work. A concept album tells a continuous story or explores a single subject across all tracks. Double albums spread across two discs for extended works. The album format has shaped how artists, producers, and listeners think about music — as a complete artistic statement rather than a collection of singles. In the streaming era, the album's dominance has been challenged by playlists and single releases, but it remains the primary format for major artistic statements.
The Beatles' Sgt. Pepper's Lonely Hearts Club Band (1967) is often credited as the first true concept album, though earlier examples exist.
