The Clockwork Prologue [1] is the seventh studio album by the English progressive rock band Gandalf's Fist.

Released on 1 July 2019, it is a two disc spanning rock-opera interspersed with a professionally acted radio play between the actual songs.

The album is a two-part "Expansion Pack"[2] to their previous album, The Clockwork Fable, featuring an expanded set of the original cast and performers, and providing more characters and storylines alongside the original story.

Sea of Tranquility's Steven Reid wrote "[...] none of this would matter if the music wasn’t up to snuff, but whether encountering the languid surge of "The Waxwork Downs", the grandiose Uriah Heep meets Iron Maiden styled "Leader of Men", the more Saracen-like "Wardens" or the glorious folk prog workout that is "Supplies for the Festivities", there's not a cog that isn't turning perfectly.

[...] In adding to the Cogtopolis storyline, it builds a little flesh on the original story, and what was an epic listen evolves into a saga.
