There are surely a lot more, especially American

Poe Through The Glass Prism. Long time since I heard this, but either Poe's poems set to psych pop music, or very heavily influence.

Wind In The Willows - Debbie Harry's first hippy pop band from 1968, I think there is a track with narration from the book, but I could be wrong.

Mr Flood's Party. Brilliant US psych LP, named after the book of poetry by Edwin Arlington Robinson, though not sure if further connections in the songs.

David Axelrod - Songs Of Innocence and Songs Of Experience - 2 LPs 'inspired by' William Blake's poetry volumes, likewise The Priests Of The Raven Of Dawn by The Open Window.
