Progressive rock (sometimes shortened to prog rock, prog, or progrock) is a subgenre of rock music which arose in the late 1960s, reached the peak of its popularity in the 1970s, and continues as a musical form to this day.
Progressive rock artists reject the limitations of popular music and aspire to create music for serious listening, often aspiring to the sophistication of jazz and classical music, sometimes incorporating folk and world music influences in as well.
It is musical dynamics, as well as the virtuosity of the musicians, which most distinguishes progressive rock. As with its counterpart, progressive jazz, progressive rock is very much a musician's form of music, designed to be analyzed, studied and appreciated by knowledgeable listeners, as opposed to many other types of rock music. Although many progressive rock artists have enjoyed phenomenal success, progressive rock is by no means a casual form of music, and by nature appeals to a more specialized set of listeners than the broad target audiences of pop music.
