Thunder Perfect Mind is another of Tibet's experimental neo-folk albums that manages to be both haunting and beautiful as it caresses your ears with a velvet death shroud. It's the poet at his most sublime and personal. You don't need a knowledge of the Gnostic text from which it takes its name to appreciate the music. It's mostly acoustic guitar with quiet strings. Occasional female backing vocals from the always welcome Rose McDowall accompany the poetics, she brings a gothic serenity to the melodies. I wish she'd stayed permanently.
