The Trans-Siberian Orchestra (TSO) was formed in 1996 by Paul O'Neill. The music genre is traditionally rock opera, but recently they invented rock theater. There are 34 members in the band. They are best known for their Christmas music. You can check out their CD The Lost Christmas Eve, which was the last installment in the trilogy, from the library.
They started touring in 1999, and in fact they have two shows coming up on Thursday, December 15th at the Bradley Center in Milwaukee. One is at 4 pm and the other is at 8 pm. I've seen them twice in concert and they are amazing! They have an awesome laser and fire show to go along with their excellent music and story!
