Progressive rock, also known as prog rock or prog, is a rock music subgenre that originated in the United Kingdom, with further developments in Germany, Italy, and France, throughout the mid-to-late 1960s and 1970s. It developed from psychedelic rock and originated, similarly to art rock, as an attempt to give greater artistic weight and credibility to rock music.
