This year for its annual fall/winter tour, the progressive rock group Trans-Siberian Orchestra will revisit The Ghosts of Christmas Eve, a conceptual show that centers on a runaway who breaks into a vaudeville theater on Christmas Eve. The rock opera features tunes such as "Christmas Eve/Sarajevo 12/24," "O’ Come All Ye Faithful," "Good King Joy," "Christmas Canon," "Music Box Blues," "Promises To Keep," and "This Christmas Day." Performances take place today at 3 and 7:30 p.m. at Rocket Mortgage FieldHouse.
