Demons of Ludlow on AllMovie

Wisconsin "B"-movie wizard Bill Rebane (the mastermind behind Monster a Go-Go! and The Giant Spider Invasion) cranked out this occult cheapie, set in the New England burg of Ludlow, which is cursed by the malevolent spirit of an executed warlock. The foul fellow returns with his demonic armies to wreak havoc on the town during its Bicentennial festivities; the title nasties accomplish this by animating a variety of weird objects -- including a piano, which serves as a vessel for the warlock's soul and triggers supernatural deaths when it's played. Overlooking the fact that the basic premise borrows heavily from John Carpenter's The Fog, there is little original material here to keep one's interest. The theme of vengeful colonial ghosts was better served in Ulli Lommel's The Devonsville Terror, on which Rebane served as associate producer.
