MacLeod's description:

Genre: Soundtrack
Length: 1:04
Instruments: Strings, Chimes, Tympani, Flute, Bass Clarinet, Bassoon, Oboe
Tempo: 65

Full of rhythmic strings and woodwinds in the lower registers, the high pitched violin that edges in and out of tune is unnerving and eerie. The pounding bass drums and church bells ring throughout, a symbol of impending doom. This music draws the line between being beautiful and frighteningly dystopian.
