Paul O'Neill had worked in the music industry a long time, developing a relationship with the progressive metal band, Savatage, as a co-writer and producer and bonding over their fusion of classical music and hard rock. O'Neill eventually started his own band and recruited Jon Oliva, Robert Kinkel, and Al Pitrelli to produce rock operas, their first being Christmas Eve and Other Stories. The themed album and following tour dates were so successful that Trans-Siberian Orchestra decided to repeat the winning on The Christmas Attic and The Lost Christmas Eve, thus completing their "Christmas Trilogy." Not limiting their operas to just one season, Trans-Siberian Orchestra released Beethoven's Last Night, which combines fact and fiction to tell the tale of Beethoven's deal with the devil the night he finished his tenth symphony. Trans-Siberian Orchestra's latest album, Night Castle, tells the story of a soldier, his true love that he knew for just one night, and the daughter he never met. The album went gold inside a year and has proven to audiences that the band's rock operas contain truly great stories.
