Progressive rock, also referred to as prog rock, prog-rock, or simply prog, is a rock music subgenre which originated in the United Kingdom, with further developments in Germany, Italy, and France, throughout the mid to late 1960s and 1970s. Developing from psychedelic rock, progressive rock originated, similarly to art rock, as a British attempt to give greater artistic weight and credibility to rock music. Progressive rock intended to break the boundaries of traditional rock music by bringing in a greater and more eclectic range of influences, including free-form and experimental compositional methods, as well as new technological innovations. It was mostly characterized by the break-up of the classic 3-minute song, replaced by long suites sometime as long as a whole LP side, rife with symphonic influences, extended and diluted musical themes, fantasy-like ambience and lyrics, and ample, very rich sounds and productions. Progressive rock saw a high level of popularity throughout the 1970s, especially in the middle of the decade, with bands such as Pink Floyd, Yes, King Crimson, Genesis, and Emerson, Lake & Palmer being the most recognizable champions of the style, and a galaxy of lesser acts revolving around the genre; at some point, even acts already known for different styles, such as Jethro Tull and Deep Purple were associated with it. Battling in popularity with the glam rock movement, prog started to fade in popularity by the second half of the decade, with the rawer and more minimalistic punk rock growing in popularity. Nevertheless, progressive rock bands were able to achieve commercial success well into the 1980s, albeit with changed lineups and more compact song structures. By the turn of the 21st century, it witnessed a revival, often known as new prog, and has, ever since, enjoyed a cult following. The genre has influenced several other styles, ranging from krautrock to neo-classical metal; it has also fused with several other forms of rock music to create sub-genres, including progressive metal.
