Yeah, Björk's music is 'post' — post-rock, post-apocalyptic, flashily futuristic in tone. But it's also "pre," tapping emotions untamed by rational thought. The electronic soundscapes she creates on Post, with the help of English dance-floor stars like Nellee Hooper, Tricky and Howie B., give her lots of room to roam. And she goes everywhere, from the junk-filled cliff top of the whimsical "Hyper-Ballad" to the psychic deep forest of "Isobel," in songs that link the rhythms of early drum-and-bass to the vocal lines of Icelandic folk singing, with a dash of musical comedy thrown in for a lark. Inventing her own genre, Björk presents what she calls "an army of me" — the many battling voices inside one woman's hyperactive brain.
