Long renowned for selling more concert tickets than albums, Trans-Siberian Orchestra united a 60-piece orchestra plus chorus with the talents of Paul O'Neill, a veteran hard rock producer. The group released its debut album, Christmas Eve and Other Stories, just in time for the 1996 holiday season; it eventually sold three-times platinum in the United States. The Christmas Attic followed in 1998, and two years later the group issued its first non-seasonal recording, Beethoven's Last Night.
In 2004, the group returned with its fourth album, The Lost Christmas Eve, which produced its best sales in the U.S. since the debut. Trans-Siberian Orchestra then collected all its Christmas recordings on the three-CD/one-DVD collection Christmas Trilogy. In 2009, after a five-year hiatus, the group returned with the two-disc Night Castle, a non-holiday-related concept album. A five-song EP, Dreams of Fireflies (On a Christmas Night), followed in 2012. Letters from the Labyrinth, their first full-length in five years and a rare non-concept album, appeared in 2015. ~ John Bush, Rovi
