Hard rock producer Paul O'Neill, renowned for his work with Aerosmith and Savatage, teamed with the latter band's Jon Oliva to create Trans-Siberian Orchestra, an inspired fusion of classical music and rock-opera pageantry. Their first two releases are visionary and timeless Christmas-themed concept albums, spotlighting lead guitars and classical string sections alike, and they became instant contemporary holiday classics. 2004's The Lost Christmas Eve, which completes their symphonic rock Yuletide triology, underscores Billboard's recent comment that TSO "seems to be turning into a Christmas tradition."
