Progressive and art rock made the album the main space for long-form composition, conceptual storytelling and studio experimentation. Classical influence, jazz, synthesizers and complex structures all became part of the vocabulary.
Major groups
Pink Floyd, Genesis, Yes, King Crimson and Roxy Music represented very different approaches—from atmospheric concept albums and theatrical narratives to virtuosity and art-school experimentation.

Long tracks, recurring themes and elaborate production depended on the LP format and encouraged listeners to experience records as complete works.
Why it matters
The genre expanded rock’s compositional ambitions and influenced metal, electronic music, art pop and later experimental scenes.
