Answer: The Who
When you think “rock opera,” you inevitably think of The Who. They made a name for themselves with their energetic performances and wild antics, paving the way for many early punk bands. In fact, The Who set a world record for the loudest rock concert during their 1976 performance in London. They held the record for eight years until the Guinness Book of World Records rescinded the title so as not to promote dangerous listening habits. How very un-punk of them.
