This came out in 1999 – or at least that’s when I got it. Here’s what I said about it back then (with some minor editing):
Normally, I don’t bother with the many soundtracks that come out weeks (or sometimes, even months) after their films.
But this companion disc to Spike Jonze’s brilliantly twisted pic — about a puppeteer who finds a portal into the titular actor’s brain — is as endearingly weird as the film. The angelic, haunting strains of the new Björk track Amphibian begin and end the album. Between are: A dozen orchestral vignettes by composer Carter Burwell, each brimming with minor-key gloom and ominous rumblings; a sly trip-hop ditty whose refrain consists only the single word “Malkovich”; snippets from the film’s demented script; an audio clip of Burwell explaining the plot to a baffled orchestra; and even two video trailers. It’ll get inside your head.
