2004 - 2007: Mes Courants Électriques, First Tour & pregnancy

In 2003, Alizée returned with her second album Mes Courants Électriques (My Electric Currents).[16] With the release of this album, she changed her image from a "Lolita" to that of a more toned-down teenager. This album was also written by Farmer and Boutonnat. While it had some success in and outside France, this second album, featuring English versions of four tracks, was not as well-received as her first one, Gourmandises. It sold 400,000 copies in France.

The first single from this album, "J'en ai marre!" (also known as "Mon bain de mousse" in Japan) was released in 2003. The music video for this shows Alizée in a glass cage, singing while having water splashed on her. The plexiglass cage, 3 by 3 meters in dimension, was constructed in a Parisian studio, and the shooting of the video took two days.[12] An English-language version of this song, titled "I'm Fed Up!", was also released, and featured similar visuals for the music video.

The other singles from this album were "J'ai pas vingt ans" and "À contre-courant". Like "J'en ai marre!", "J'ai pas vingt ans", "Youpidou" and "Amélie m'a dit" also had English versions. The video for "J'ai pas vingt ans" ("I'm Not Twenty") resembles the ambience of a concert with Alizée dancing in the midst of several other dancers.[12] "À contre-courant", the last single from this album, was shot in an abandoned coal factory.[12] Unlike the other two singles, there was no English-language rendition of this song.

Following the release of Mes Courants Électriques, Alizée went on a countrywide tour of France, along with a performance each in Belgium and Switzerland, during the second half of 2003. The tour started off with a performance on 26 August 2003 in Paris.[4][17] It concluded with her performance on the eve of 17 January 2004 at the Le Zénith concert hall in Paris and had covered major cities including Lyon, Rouen, Lille, Grenoble and Dijon.[4]

A live CD and DVD, titled Alizée En Concert, composed of selected performances from her tour, was launched a year later in the fall of 2004.[18] The audio CD contained tracks, taken from her two studio albums. The DVD featured video footage of the same performances as on the CD, along with bonus footage of her rehearsals.

The compilation was re-released in early 2007 in Mexico by Universal Music as a CD+DVD release,[19] following the featuring of the songs in local radio stations. With the re-release and renewed interest, the songs climbed up the music charts in the country. The album became a hit, peaking at number four in the International Chart on 28 May 2007,[20] and number eight on the main albums chart. En concert has a Gold certification for shipments over 50,000 copies only in Mexico.[21]
