Jean Michel Jarre's concert in Paris on 14th July 1990 entered the record books as having attracted the biggest ever crowd to a free rock concert. Over two million exuberant fans crammed the narrow streets of central Paris to enjoy an evening of great music and stunning visual effects.

... This concert spectacular transformed the skyscrapers and surrounding buildings of 'La Defense' into living sculptures through the magic of giant projections, spectacular lighting effects, lasers and fireworks, all synchronised with the music from the central pyramidical stage. A harmonious combination of the past and the present, the baroque and the high tech, ecology and technology, a vision of the Opera of the 21st century.

In this instance, unfortunately, "HQ" means "Higher Quality" rather than "High Quality".

... In 10 parts. :-(
