The Trans Siberian Orchestra is a progressive rock/metal insturmental band that puts a rocking touch on old classical music favorites from Beethoven, Bach, Mozart, Brahms, and Tchaikovsy. That also means they make rocking Christmas instrumental music. From what I hear they are amazing to experience live as their concerts are accompanied by strobe lights, lasers,and pyro. Here are some of their Christmas rockers.
Mad Russian's Christmas
Siberian Sleigh Ride
Wizards in Winter
March of the Kings/Hark The Herald Angel
Christmas Eve/Saravejo 12/24
Even if you are not a fan of Christmas Music you have to admit these sound really badass for Christmas songs. Look them up on YouTube and see their live performances or see them live when they come near you. They look more badass in concert than in their recordings!
