Progressive Rock
Rock musicians stretching the format until a song could work more like a suite, a conversation or a long argument.
Progressive rock developed most visibly around the turn of the 1970s, with British groups including King Crimson, Yes and Genesis using ideas from classical composition, jazz and psychedelic Rock. Recordings could move between extended instrumental passages and carefully arranged vocal sections, and albums increasingly became places for musicians to develop larger structures. There was never only one progressive-rock formula: Soft Machine's jazz-related experiments stood some distance from the symphonic writing of Yes.
What happens when the song gets longer
Changes in meter, recurring themes, intricate keyboard parts and shifting guitar textures can all play important roles. A quieter movement may return much later in an altered form; a rhythm section can interrupt rather than simply accompany the melody. Yet complexity alone is insufficient. Some of the most memorable progressive rock uses a clear, direct passage to give its longer pieces emotional weight.
An important parent with several exits
Progressive Metal later drew on this compositional freedom while working with heavier riffs. Math Rock uses irregular rhythms in a different historical network. Post-Rock can also develop pieces over long stretches without adopting progressive rock's traditional virtuosity. Their overlaps are real, but strict ancestry should be assigned only when the underlying relationship is defensible.
