Godzilla vs. Gigan/Terror of Mechagodzilla (Ifukube, 1972/75)

Godzilla vs. Gigan
     In 1972's "Godzilla vs. Gigan" (also known as "Godzilla on Monster Island, 地球攻撃命令　ゴジラ対ガイガン, lit. "Earth Destruction Directive: Godzilla vs. Gigan"), the music score was assembled almost entirely from retracked music of previous productions using Akira Ifukube's music (many of which were not Godzilla-related).  For audience members not familiar with the source films, the approach works well enough, and the retracked cues are applied in a fairly thematic way.  The music was retracked from the following 11 productions and the cues indicated:

• THE BIG BOSS:­ M12T2, M15B
• A LIFETIME OF BUSINESS SAVVY - THE TOUGHEST GUY AROUND: The Meiji Restoration
• ATRAGON: The Film That Was Sent, The Submarine Returns to Port
• BATTLE IN OUTER SPACE: Opening, Main Title
• FRANKENSTEIN CONQUERS THE WORLD: Main Title, Search March, Encounter in the Rain, The Whereabouts of the Wrist, Search in the Fog
• KING KONG ESCAPES: Element X
• LATITUDE ZERO: Mariku and Dr. Okada
• GODZILLA VS. THE THING: Destruction of the Hamikaze Hotel, Godzilla and Nagoya, Plan B: Electrocution 
• GHIDORAH THE THREE-HEADED MONSTER: Discovery of the Meteor, The Three Giant Monsters Enter the Fray, The Two Monsters Appear in Yokohama, The Fury of the Gravity Beam
• DESTROY ALL MONSTERS: Monster Land, SY-3 Sortie, Escape From Monster Land, Major Battle at Fuji I/II
• EXPO '70 Mitsubishi exhibit: Volcano, Storm

     The only newly composed track was the end title, which was composed by Miyaguchi Danro (and sung by Ishikawa Susumu).  Since the budget and production values for the Godzilla films at this point approached that of a television series, it's more or less forgivable that the score for this feature was assembled in this way.

     Story-wise, a young artist becomes employed by designers of the under-construction Children's Land amusement park.  The artist (Gengo) meets some new friends who reveal to him that his employers are actually evil aliens.  The aliens use a special tape to call King Ghidorah and Gigan to Earth in order to wreak havoc.  Godzilla and Anguiras come to the rescue (though Anguiras gets a decidedly chilly reception on his initial reconnaissance mission).  A "Godzilla Tower" exhibit at the Children's Land park shoots lasers at Godzilla, but Gengo and his friends blow it up.  In the end the space monsters are sent fleeing through the clever teamwork employed by the Earth protectors.

     The score to Godzilla vs. Gigan has seen several releases over the years.  The below table is based on the main score tracks from Godzilla Perfect Box 3, Disc 2, which also includes 7 bonus tracks of karaoke and alternate versions at the end.

Terror of Mechagodzilla
     In 1975, the initial wave of Godzilla films (the Shōwa series) ended with "Terror of Mechagodzilla" (メカゴジラの逆襲, lit. "Counterattack of Mechagodzilla").  For this final 70's entry, Akira Ifukube returned to deliver an all-new original score, 21 years after his first Godzilla film.  This score notable revives the Godzilla March from the first film, in place of Godzilla's more often used Terror and Resurrection themes from the last few films.

     The story is a somewhat familiar one:  a mysterious new monster, Titanosaurus, destroys a research submarine which brings about an investigation by Interpol.  One of the investigators, Ichinose, meets and falls in love with Katsura, the daughter of a mad scientist.  The mad scientist aids evil aliens in their plans to use giant monsters to wreak havoc on Earth.  In an earlier incident, the aliens saved Katsura's life, but also made her into a cyborg (and giving her the ability to control a rebuilt Mechagodzilla).  In the end, Katsura takes her own life to disable Mechagodzilla.  Godzilla defeats Mechagodzilla and Titanosaurus.

     "Terror of Mechagodzilla" makes up for the retracked "Godzilla vs Gigan" by providing 6 new themes, often with multiple parts (such as a declarative figure and a fanfare).  In track 7, "Mechagodzilla II", Ifukube cleverly puts Katsura's Cyborg theme in between Mechagodzilla theme statements, giving a clue that Katsura will later be turned into the control mechanism at the heart of the bionic behemoth.

• Titanosaurus Theme A:
• 4-note zigzag, 5-note rising (usually repeated)
• 2-part fanfare (7 + 6)
• Titanosaurus Theme B:
• 1-note, 5-note rising (usually repeated)
• Rising-falling staccato phrase 
• Mechagodzilla theme: 2-part fanfare (5 + 4), 5-note falling-rising figure repeated
• Godzilla March: descending 3-note figures, ending in rhythmic accents (from "Godzilla").
• Katsura Human Theme: in 2 phrases (7 + 5)
• Katsura Cyborg Theme: in 2 phrases (7 + 4), with the last 4 note phrase sometimes echoed 

     The score to Terror of Mechagodzilla has seen several releases over the years.  The below table is based on the main score tracks from Godzilla Perfect Box 3, Disc 5, which also includes 2 bonus track alternate takes at the end.

Invasion of Astro-Monster / Destroy All Monsters (Ifukube, 1965/1968)

     Invasion of Astro-Monster and Destroy All Monsters are the 6th and 9th entries in the Godzilla film series, as well as the 5th and 6th instance where Akira Ifukube provided a Godzilla score (it was also Toho's 20th overall giant monster film).  Interestingly, they both involve aliens taking control of giant monsters and using them against the Earth.  They also both feature King Ghidorah as the "final monster", after the humans turn the monsters back against their alien controllers.  For this reason it's logical that many of the alien themes introduced in "Invasion" return in slight variations in "Destroy".  In fact, it's very possible that the Xiliens and the Kilaaks are the same aliens, but from different time periods.  The mind boggles.

Invasion of Astro-Monster, 1965 (Also: Monster Zero, 怪獣大戦争, "Great Monster War")
     This was the first Godzilla film in which aliens have a strong presence (as opposed to gangsters, foreign assassins or commercial entrepreneurs).  For this reason Ifukube was able to incorporate even more interesting textures.  In addition to the kaiju (giant monster) themes returning from Ghidorah the Three-Headed Monster (Ghidorah theme with tail, Rodan theme, Terror motif, Resurrection theme), Ifukube added the Monster fanfare (a stinger similar to the Monster cadence from Mothra vs Godzilla) and a new Monster Control theme.  The humans were assigned a new Monster Zero March, and the alien Xiliens were portrayed with suspense textures based on a Planet X motif and an exotic 7-note Xilien theme, both often making use of high string noises (sul ponticello), alto flute, xylophone, vibraphone, "wobbly" synth-like tones and muted brass.

     The score to Invasion of Astro-Monster has seen several releases over the years.  The below table is based on the main score tracks from the Godzilla Perfect Box 2, Disc 1, which also includes 10 bonus tracks at the end (an alternate take and various takes of source music).

Destroy All Monsters, 1968 (怪獣総進撃, "Attack of the Marching Monsters")

     Ifukube returned and further developed the ideas he explored in Invasion of Astro-Monster (see above), especially textures related to alien invaders.  Even though there are 11 giant monsters appearing, Ifukube basically reused the monster themes he'd developed in the previous film (with some variations for Rodan's theme in particular and reprisals of Astro-Monster's Monster Control theme).

     The new themes for the humans include the Destroy All Monsters March, the memorable "perpetuoso" Remote Control Destruction theme (derived from "Matsumoto City And King Ghidorah" from 1964's "Ghidorah, the 3-Headed Monster") and the Moonbase theme.  The Kilaak aliens receive the return of the Xilien theme from "Invasion" (perhaps they are related?), a Kilaak "choir" texture, a brief Escape theme and the Monster Land theme (all of which are more or less derived from the Xilien theme/scale).  A new Destroy All Monsters theme (Main Title, All Monsters Attack) rounds out the new themes.  The Planet X motif from "Invasion" also returns fairly frequently here, as well as the Monster Control theme (appropriately enough).  As usual, even though the themes for the individual monsters also recur fairly frequently, they are often written in different tempos and orchestrations.

     The score to Destroy All Monsters has seen several releases over the years.  The below table is based on the main score tracks from the Godzilla Perfect Box 2, Disc 4, which also includes 11 bonus tracks at the end of retracked cues and alternate takes.  In the table below I put the retracked bonus cues in their chronologically-correct placement.
