I picked this up in France having heard one track on the radio, and have been listening to it repeatedly since then. It's a thoroughly fresh and surprising listen from start to finish.
Gainsbourg's voice is not a strident, confident and trained instrument, but her subtle, tender, and at times timid delivery is very engaging. She was apparently so nervous at times recording the album that she sang from beneath a sheet. She need not have worried.
The duo that form Air provide the soundtrack, while Jarvis Cocker and Neil Hannon provide the lyrics. All have excelled themselves: the melodies are gorgeous, at times swooping and exultant, at times minimal and delicate; the lyrics are subtle and beguiling.
From first listening it struck me that this album is one of those collaborations that rarely comes along, which is pure magic. The chemistry between the collaborators was obviously just right, and has resulted in a fine creation.
