The En Concert Tour was the first concert tour of the French recording artist Alizée. It started at the famous Olympia music hall in Paris. The tour was generally well received although not all of the concerts sold out. The original plan had 43 dates but two of them got cancelled. Near the end of the tour, one extra concert date was added to bring the tour back to Paris, this time at the huge Zénith de Paris music hall. She also had one concert in both Switzerland and Belgium. With the two cancelled and one added date, the total number of concerts held was 42.
