Combining the sophistication of a 60-piece orchestra with the explosive sonic punch of a heavy metal band, this Christmas celebration from Trans-Siberian Orchestra has everything we love about the holiday season. TSO's hard-chugging "Ornament" is somehow both solemn and raucous, like an aria from an opulent rock opera, while their contemplative "Christmas/Sarajevo 12/24" combines elements of the familiar "Carol of the Bells" with an original tune for an epic onslaught of hard-rocking pageantry and joy.
