Trans-Siberian Orchestra (TSO) is an American progressive rock band founded around 1993 by
producer, composer, and lyricist Paul O'Neill, who brought together Jon Oliva and Al Pitrelli
(both members of Savatage) 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 second album, The Christmas Attic the year previous. 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, their two-disc Night Castle and
Letters From the Labyrinth.
