In the range of three octaves, sung by me in 13 tracks. Not completely in tune. The first one is unedited sound. The second is transposed an octave lower. The third is transposed two octaves lower. In the fourth all the latter are sounded together (39 voices). The transposing makes a peculiar effect to the voice specially in the second (12 semitone) transposition.
Night sounds of night, mainly crickets, recorded at san francisco libre, nicaragua. You will also hear low human voices and some cars far away. Listen through the loops, because perhaps you will need to make some adjustments.
