As is appropriate for the "hallowed" month of October, this month's Underappreciated Music is a musical interpretation of Edgar Alan Poe's classic poem "The Raven" by the late 60s pysch band Glass Prism.
Glass Prism's first two albums were devoted to songs based on Poe's works, a perfect fit for their Procol Harem-ish brand of rock. I first heard the song just a couple of years ago and have included it in my Halloween playlists ever since.
Take a a listen for yourself and you may do the same. Enjoy!
