It's Fantastic !

Berlioz's Symphonie Fantastique is a well-known classic with a wonderfully creepy ending -- movement 5, the "Dream of a Witches' Sabbath," featuring the "Dies Irae" theme.   Here we have a piano transcription.

The tracks:
1. I. Reveries - Passions
2. II. Un Bal
3. III. Scene Aux Champs
4. IV. Marche Au Supplice
5. V. Songe D'une Nuit Du Sabbat
