Lossless Progressive Rock Flac Music

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 pop (rather than psychedelic rock, as is often stated) and originated, similarly to art rock, as an attempt to give greater artistic weight and credibility to rock music.
