I had the luck to go to a live concert by Jean Michel Jarre in my city. The concert was in a new auditorium with a superb acoustic. I was also lucky enough to be only a few meters from the stage, full of those analog synths that he used originally to record Oxygene.
I grew up with his music, so this concert was absolutely special and unforgettable for me.
I highly recommend you to go to see a live concert by Jean Michel Jarre if you have the chance.
