The 26th concert was amazing. You could see that Jarre was having a blast and was constantly improvising and changing the songs. Which made it harder for the 3 other musicians to follow him. You could see Francis Rimbert often shake his head or laughing indicating that Jarre wasn't playing what he was supposed to play. For example, the solo in Oxygene 5 kept on going and it took a while before Jarre started playing the melody of Oxygene 6. It made it a truly live performance.
The song that they played between oxygene 6 and 7 was new and very good. It was real arpegiator heaven, layering arpegios and sequences one after another starting with the Jupiter 4, then the Oscar and then the Digisequencer. I often had the feeling I was listening to a Tangerine Dream concert in 1978, same style of music.
