First up, I will admit I don't know French, but not knowing French doesn't spoil this album at all.
Right from the start you get a very enjoyable track, then that leads to another great sounding track and another and so on. It goes like this for about 17 tracks. It might be more, I'm in and out of a coma to be honest, so the meds make things a bit woozy.
Of course it would be nice to hear them sing in English, it would be nice to hear these songs in English, but then I'll take some of the blame for never learning French. It's my fault, ok? God, I feel terrible now. I'm so lazy, I never amounted to anything.
So we have a beautifully sung album sung in a weird language, that being the case, if French doesn't bother you, buy it, sit back, listen, enjoy.
