Visit www.animusic.com if you're interested in watching this amazing Animusic video, along with seven, fourteen, or more other Animusic videos, with much better picture and sound quality on DVD. Animusic is a computer animation company specializing in the visualization of MIDI-based music.

This is a computer generated video showing robots and self-operating instruments playing classical music inside a large building. There are pipe organs, clarinets, and flutes that emit light-beams as they play notes; some trumpets and tubas affixed to walls, and they stick out when they play individually; a one-stringed rock bass guitar played by robot fingers, two of which slide up and down its neck; a yellow synthesizer; and a drum set, and two large, curved instruments, the hammered dulcimer and the xylophone, played by robots that pivot and slide back and forth to hit their mark.

The music on this piece is from 3 movements of Mussorgsky's 1874 "Pictures at an Exhibition" ten-movement piano suite.
They are:
"Promenade" [from start to 1:38]
"Hut on Fowl's Legs (Baba Yaga)" [from 1:38 to 3:45]
"The Great Gate of Kiev" [from 3:45 to end]

Do you notice the picture on the bass drums? It is a drawing of the Great Gate of Kiev complete with a bell tower to its right.

The music sounds like Emerson, Lake & Palmer's version of "Pictures at an Exhibition".
