Progressive rock emerged in Britain in the late 1960s and peaked in the early 1970s. It was characterized by extended musical arrangements that drew on classical structures and included elements like quoting classical excerpts. The six main bands of the first wave of progressive rock were Yes, Genesis, Emerson Lake and Palmer, Jethro Tull, King Crimson, and Pink Floyd. Progressive rock shows became grand multimedia spectacles by the mid-1970s with huge screens, costumes, and light shows. Though the genre declined by 1980, it had a resurgence in the 2000s led by artists like Steven Wilson who carried on its legacy of fusing rock and classical music into concept albums and elaborate live performances.
