Unlike most of the rock bands on this list, Jean Michel Jarre is a French composer who made a name for himself on keyboard and became an instrumental part of the electronic and techno music scenes in the late 70's and 1980's.
Over the decades, Jarre has become one of the most popular live acts in Europe, hosting multiple shows in Paris, France, and Houston, Texas, which brought in more than a million attendees each.
His largest concert ever took place at the Moscow State University, Russia, in 1997. With an estimated attendance of 3.5 million people, the event quickly matched the record for the largest open-air concert ever performed.
Only our next entry has come anywhere close to matching that figure. Jean Michel Jarre remained the only artist to continuously hold record-breaking concerts through the 20th century.
