"Progressive rock (often shortened to prog; sometimes called art rock, classical rock or symphonic rock) is a broad genre of rock music that developed in the United Kingdom and United States throughout the mid- to late 1960s. Initially termed "progressive pop", the style was an outgrowth of psychedelic bands who abandoned standard pop traditions in favour of instrumentation and compositional techniques more frequently associated with jazz, folk, or classical music. Additional elements contributed to its "progressive" label: lyrics were more poetic, technology was harnessed for new sounds, music approached the condition of "art", and the studio, rather than the stage, became the focus of musical activity, which often involved creating music for listening rather than dancing." - (en.wikipedia.org 08.03.2021)
