Additionally, there were speaker clusters halfway back on the left side of the hall, halfway back on the right side of the hall, and directly opposite the stage in the back of the hall. Since our seats were in the middle on the floor, we were centered right in the middle of all four speaker clusters. It would be an interesting concert sitting in the the middle of a quadraphonic sound system. The show began with the house lights being turned off. The projection screen then came to life with a rapidly growing silver ball on it.
Machine sounds poured from all the speakers as the band made it's entrance onto the stage.
The bass pulse started and the band began playing Welcome to the Machine . Roger was in a good mood, smiling as he welcomed the audience to the machine. And the band was in fine form. The animation on the screen continued throughout the song and had mechanical insects marching across a terrain, a head growing out of the ground and being severed at the neck only to lie on the ground with the skin rotting before our very eyes until only a skull remained, futuristic cities in which the buildings crack and bleed, the blood becoming a river in which the crests of the waves turn into hands groping towards the sky and, finally, as the river becomes a sea surrounding a spire, the spire ignites into a rocket which launches into space, only to reunite with the giant silver ball that appeared at the start of the film. Quite an impressive opening, bringing back memories of the 1977 Pink Floyd tour.
