A bit closer to home (Belgium), Hans De Ley creates some very unusual abstract soundscapes, using only his voice and a seemingly limitless arsenal of DSP algorithms. The result is more than just a monotone array of singing chimpansees, and proves that the voice's range can outperform many a synth.
The immense spectrum of sounds accessed through this method clearly offers a lot of possibilities, which Hans puts to use without ever repeating himself. The 6 tracks in question are enormous continual soundtransformations which could not have been labelled better than "mouthscapes". A very unique direction that deserves to be further inspected.
