Marco Rossi of Record Collector said that "1971's Galactic Zoo Dossier is splenetic and heroically unravelled acid-rock, which occasionally snaps into focus to startling effect.

[3] Tait was fired thereafter due to him wanting the band to follow a looser, jazzier sound, with Andrew McCulloch of King Crimson replacing him.

Brown had been living in the U.S. just before the end of his previous band, and was inspired by some of the things he'd seen on American television, namely footage of the Vietnam War and reports on the death of senator Robert F.

It was looking at a spiritual quest in the context of earning money, assassination, wrongful arrests, and it was posed in terms of us all being prisoners in a Galactic Zoo.

Living in such a wildly extreme country, where you could witness opposite viewpoints all the time made me think about the way we behave as human beings.

According to Roger Smyth, in a review of the album for Salient Magazine, "Galactic Zoo Dossier starts with deceptive timidity with a religious message (tongue held firmly in cheek) audible from amid a confused pile up of voices, but then proceeds to range (or perhaps ramble) over a large number of modern musical forms.

"[6] The majority of the album segues seamlessly together, similar to later releases by other bands, such as Pink Floyd's The Dark Side of the Moon or XTC's Skylarking.

For the title track "Galactic Zoo", Brown "told the guys to imagine they were creatures stuck in one area and running around trying [sic] escape, in a constant state of motion forever attempting to find a way out."

“Inconstant Wisdom” contains a section that would later become “Creep”, while “Water” (unrelated to their 1972 song of the same name) has elements that would be reshaped into “No Time” lyrically and “Metal Monster” musically, and “The Finger” was an early version of “Sunrise”.

[citation needed] The fourth track on the album, "Metal Monster", is notable for having an effect that sounds similar to that of a CD skipping.

A live medley of "Internal Messenger", "Creation", and "Gypsy Escape", performed at the 1971 Glastonbury Festival, was released in the 1972 film about the event and its soundtrack.

It was commercially unsuccessful, and as a result, the band was marketed in the United States as Arthur Brown's Kingdom Come, in hopes that including his name would boost sales.

[citation needed] Galactic Zoo Dossier was a commercial flop upon release, however it has garnered some praise in recent years.

In the AllMusic review for the album, it notes the drastic difference between Kingdom Come and the Crazy World of Arthur Brown, stating that "While there was still a carnivalesque classical-jazz-rock organ base to the arrangements, guitar also took a prominent role, and the melodies were far gloomier and more obtuse."

Record Collector notes that you'll "witness the super-tight interplay of Internal Messenger, the deft jazz-rock dexterity of No Time, and the prog-lite prestidigitation of the instrumental Gypsy Escape."
