is primarily an a capella group. Mahk Jchi, one of their signature songs, has been put 
music. I derived the chords below from one of the recordings with it.

English Translation:
A hundred years have passed
Yet I hear the distant beat of my father's drums.
I hear his drums throughout the land.
His beat I feel within my heart.
The drum shall beat
so my heart shall beat.
And I shall live a hundred thousand years.
