Paul O'Neill founded the rock band Trans-Siberian Orchestra 20 years ago, and for more than a decade, Bryan Hartley has been designing the band's annual holiday tour. The 2015 tour, titled The Ghosts Of Christmas Eve, featured lighting gear from VER Lighting, video from PRG, and lasers and pyro from Pyrotek Special Effects. The production involved more than 500 people, 34 semi-trailers, and 18 tour buses, according to TSO's Facebook page. TSO shared the time lapse video below of everything that went into a single show.
