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."
