If you can't get enough of Mannheim Steamroller's merge of classic and rock, head out to see them Monday at Hershey Theatre, 15 E. Caracas Ave., Hershey. The group's 1984 Christmas album became a runaway hit, resulting in the group being one of the biggest selling Christmas music artists in history. The show will mix Renaissance instruments with rock 'n' roll beats, and include state-of-the-art multimedia effects. Tickets for the 8 p.m. show are $55, $65 and $75.
