MANCHESTER – Trans-Siberian Orchestra (TSO) is back in town and ready to rock the holidays.

In its 20 consecutive year of touring, TSO brings it multisensory spectacle to the SNHU Arena on Elm Street for shows at 3 and 8 p.m. Friday.

The production is based on “The Ghosts of Christmas Eve,” by the group’s late founder, composer and lyricist Paul O’Neill. The story, which was both a multiplatinum DVD and a long-running PBS fundraiser, centers on a runaway who finds her way into a mysterious abandoned theater.

This year’s tour will include new effects and a new staging design. Expect lights, flames, high-flying guitar licks and more.

The rock opera also features enduring fan-favorites 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.”

As in all previous years, a portion of every ticket sold benefits select local charities. To date, more than $15 million has been distributed from TSO to worthy charities all across North America.

Rhino Entertainment last month released a 20th anniversary edition of The Christmas Attic on CD and digital format, and a vinyl version came out earlier this month. The second installment in The Christmas Trilogy tells the story of a little girl who spends nights in an attic filled with yuletide reveries, while guitar solos and choral vocals soar over a rock orchestral backing across 16 tracks, including a previously unreleased on CD and vinyl version of “Christmas Jam (Live).”

Tickets to Friday’s shows range from $47.50 to $79.50. For more information, visit snhuarena.com or call (800) 745-3000.
