Talkie Walkie is rich, somber headphone pop. It's beautiful, it's magical, it's disorienting, and it's over in an hour. Nigel Godrich, the man behind Radiohead's OK Computer and Beck's Mutations, helps build the spacious grandeur of the music. The album's crowning achievement, "Alpha Beta Gaga," takes the happiest melody Air have ever composed and warps it with a cheerfully whistled chorus that sounds right at home in an alien musical environment full of bright pizzicato strings, theremin, and even a banjo. It's an artificial paradise that allows the strangest emotions to flourish together.
