Progressive rock, also known as prog rock, prog-rock or simply prog, is a rock music subgenre which originated in the United Kingdom, with further developments in the United States, Germany and Italy, throughout the mid to late 1960s and 70s. 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.
Progressive rock saw a high level of popularity throughout the 1970s, especially in the mid-part of the decade, with bands such as Pink Floyd, Genesis, King Crimson, Yes, Jethro Tull and Emerson, Lake & Palmer. Progressive rock started to fade in popularity by the latter part of the decade, with the rawer and more minimalistic punk rock growing in popularity;never
