Grade: A

What a miracle the KLF were: an elaborate practical joke at the expense of the music industry, seemingly both wholly cynical and completely sincere, who for a short period at the start of the 1990s bestrode the singles charts like a novelty colossus. A reissue of their greatest hits album wouldn’t seem cause for celebration — doesn’t the world have quite enough singles collections? — but the nature of the KLF’s disappearance (they burned a million quid and deleted their entire back catalogue) makes this unexpected reappearance a bit of an event.
