Style Rock: Progressive Rock & Symphonic Rock.
Progressive rock (or prog rock) is a rock genre that emerged in the 1960s, known for its complex structures, use of orchestral arrangements, tempo changes, technical virtuosity, and conceptual lyrics, fusing elements of rock, jazz, and classical music, privileging the album as a unitary work of art over the single radio-friendly track, with key bands such as Pink Floyd, Genesis, and King Crimson.
Symphonic rock (in English symphonic rock, or also symphonic prog) is a current within progressive rock characterized by broader and more complex sounds, with often complex scores that often use solutions borrowed from classical music.
Important English symphonic rock groups and artists included Emerson, Lake & Palmer, Genesis, Gentle Giant, early King Crimson, the Moody Blues, Rick Wakeman, Yes and Camel.
