Mostly consisting of incidental music by Jon Brion but with other tracks littered throughtout, this OST is a work of haunting beauty. A mixture of ear pricking eerieness and frantic dream like sequences make this a constant delight. Worth owning just for the brilliant reworking of the Korgi's 'Everybody's got to learn sometime' by Beck though.
I would recommend knowing the movie well before you consider purchasing this as it is one of those soundtracks that is probably best appreciated as a companion. Enjoy.
