Great for the holidays, as with all Trans-Siberian Orchestra pieces, yet based on classical music, so also fitting for any pops concert! Based on Mars, the Bringer of War from "The Planets" by Gustav Holst and In The Hall of the Mountain King by Edvard Grieg, this energetic setting of beloved favorites will rock your concert. Includes optional electric guitar, electric violin, electric bass, percussion, and piano parts. For a great opener or closer, this piece can be combined with the band arrangement by the same name for a joint performance.
