I have been aware of it through the “doors of perception” quote that created the band name The Doors, but I never had any compelling reason to read it before.
Of course when I first listened to this, I had no idea that it was literally the entire work of Blake’s piece set to music.
And I had no idea that there would be so many diverse styles of music on the album.
I’m going to focus more on the music, as I’ll address the “lyrics” later.
When the parts are done, the song turns in to a heavy metal guitar solo over some heavy chords. “Plates 5-6” is also a very clearly spoken/sung track.
