Alizée's big return to concert stage was at W9 VIP Live concert on January 9, 2008. It was almost exactly four years after her last concert, at the end of En Concert tour. This time, it wasn't completely her own concert but close enough that fans got excited. The problem was how to get tickets, as they weren't sold anywhere...
The concert took place in Strasbourg, and it was the opening concert of the brand new Zénith concert hall, the biggest in France. The tickets were given free through various sources but still very difficult to get anyway. Thankfully RMJ got his tickets and was able to attend the concert and took some nice photos, even though the photographing was strictly forbidden and the security was very thight on the entrance.
