I don't expect the kind of concert touring she did with her first two albums. Some kind of publicity touring will happen no doubt. As far as coming to the USA to perform, don't hold your breath. I don't ever see that happening, ever, not a chance.
Alizee, the third time around, is coming back to prove she still has it. Afterall she loves to perform in front of people, its her passion. I hope the buying public agrees with her and makes her next album a success!
