Most Eerie Psychedelia - H.P. Lovecraft, 'Electrollentando'

The Chicago folk-rock band H.P. Lovecraft took its name from a gothic fantasy/horror writer from the early 20th century. The band was founded by two very different musicians - guitarist and singer George Edwards, who gained his musical experience in the Chicago folk and blues circle, and Dave Michaels, a classically-trained keyboard player and singer.
The track featured here comes from the band's 1968 second album (under the simple title "H.P. Lovecraft II"), but quite recently both albums have been reissued as a single title - "Dreams in the Witch House - the Complete Philips Recordings". I chose it because it's certainly far from being a "song". But listen and judge it yourselves.
