"Imagine when he gets a big room to sing in!" That's how Trans-Siberian Orchestra founder and guitarist Al Pitrelli summed up a stunning live studio performance by Englishman Nathan James this morning on 96.5 KVKI.

Pitrelli and James were joined by vocalists Chloe Lowery and Andrew Ross, each knocking out shortened versions of their featured songs in Trans-Siberian Orchestra's "Lost Christmas Eve," which hits the CenturyLink Center in Bossier City tonight at 7:30.

Pitrelli and group spent an hour with us, performing three numbers from the iconic TSO Christmas rock opera, which has been revamped, rearranged and updated for this year's tour.

"We think it's better than ever," said Pitrelli. "Paul [O'Neil, TSO co-founder and composer] has so many new ideas, new characters and new songs. That's why we think our fans will like it more than ever."

The show, which will be introduced by yours truly, kicks off tonight at 7:30 at the CenturyLink Center in Bossier City. See you there!
