Art rock is a subgenre of rock music that originated in the 1960s with influences from art (avant-garde and classical) music. The first usage of the term, according to Merriam-Webster Online Dictionary, was in 1968. Art rock was a form of music which wanted to "extend the limits of rock & roll", and opted for a more experimental and conceptual outlook on music. Art rock took influences from several genres, notably classical music, as well as experimental rock, psychedelia, avant garde, folk, baroque pop, and, in later compositions, jazz.
