Light and sound and the combination of the two have always fascinated me. Here lies the origin of this blog – tweets about a specific moment with a specific piece of music and a specific picture associated to both. But I am just an amateur. Meet the masters of sound and light, for instance the French artist Jean-Michel Jarre. I recall my fascination at the age of 15: Jarre composed electronic music and performed it with huge laser shows. And yesterday I have seen and heard the Luxembourg pianist Francesco Tristano performing Johann Sebastian Bach’s Goldberg Variations (BWV 988) and building a towering digital city on a screen in the concert hall – projections of the music. 90 minutes of (de)light and great sound… and great fun for that prepared grand piano is one fantastic toy.
