Trans-Siberian Orchestra is an American progressive rock band founded in 1993 by producer, composer, and lyricist Paul O'Neill, who brought together Jon Oliva and Al Pitrelli and keyboardist and co-producer Robert Kinkel to form the core of the creative team. The band gained in popularity when they began touring in 1999 after completing their third rock opera, "Beethoven's Last Night." In 2007, the Washington Post referred to them as "an arena-rock juggernaut" and described their music as "Pink Floyd meets Yes and The Who at Radio City Music Hall." TSO has sold more than 10 million concert tickets and over 10 million albums. The band has released a series of rock operas: Christmas Eve and Other Stories, The Christmas Attic, Beethoven's Last Night, The Lost Christmas Eve, and their two-disc Night Castle. Trans-Siberian Orchestra is also known for their extensive charity work and elaborate concerts, which include a string section, a light show, lasers,"enough pyro to be seen from the international space station", moving trusses, video screens, and effects synchronized to music.
Both Billboard Magazine and Pollstar have ranked them as one of the top ten ticket-selling bands in the first decade of the new millennium. Their path to success was unusual in that TSO is the first major rock band to go straight to theaters and arenas, having never played at a club, never having an opening act and never being an opening act. In the fall of 2013 it was announced that they would kick off their 2014 European tour with a performance on New Year's Eve in front of over 1,000,000 fans at Berlin's Brandenburg Gate. The show would also be broadcast live to millions more on German television.
