Hall of the Mountain King is the fourth studio album by the American heavy metal band Savatage, released in 1987 under the direction of producer Paul O'Neill.

O'Neill's influence pushed Savatage to adopt a conceptual style beginning with this album.

"Prelude to Madness" is an arrangement of Grieg's "In the Hall of the Mountain King" from the Peer Gynt suite.

The intro of "Prelude to Madness" features keyboards and guitar playing "Mars, the Bringer of War" from Gustav Holst's suite, The Planets.

The song would be re-recorded by Trans-Siberian Orchestra in 2009 under the title of "The Mountain", appearing on that group's fifth studio album, Night Castle.
