Progressive rock
Progressive rock was first made in the late 1960s, but became most popular in the 1970s. It continues to be popular today, too. Progressive rock began in England and spread throughout Europe. It remains most popular in Europe, but there are several notable American and Canadian progressive rock bands. This genre was influenced by classical music and jazz fusion. Over the years, different sub-genres of progressive rock have been created, such as symphonic rock, art rock, math rock, and progressive metal.
