MacLeod's description:

Genre: Soundtrack
Length: 3:37
Instruments: Marimba, Xylophone, Percussion, Basses
Tempo: 108

One file that contains the same piece in 2 tempos; slower and faster. The slower version gives a more tribal feel - the fast one destroys that, and lends a slight edge-of-the-seat feel.
