Posteriormente en la edición mezclo de diferentes formas estas dos capas del paisaje. Las grabaciones no estan procesadas con ningún efecto. A pesar de estar en un entorno bastante aislado era casi imposible no escuchar los 60Hz del tendido eléctrico, eso si con pequeñas variaciones según el lugar.Cada track corresponde a uno de los lugares.

'''VLF''' &lt;br /&gt;
&lt;br /&gt;
During the residency I pass a few days in another area FUMAÇA a natural area and quite isolated mountain with breathtaking nature. I spend these days to experiment with the VLF receiver and  aluminum bamboo antenna. The previous days had assembled and welded the receiver [http://www.auroralchorus.com/bbb4rx3.htm BBB4 Bares Bones Basic Natural Radio,] a classic circuit designed by Stephen P. McGreevy and easy to get started in this field of listening VLF (0.1 to 15 kHz), and I built the whip style aluminum antenna of 2 meters assembled on a bamboo pole of 5 meters. The results were quite satisfactory.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
Durante la residencia pase unos dias en otra zona  FUMAÇA una zona natural de montaña y bastante aislada con una naturaleza impresionante. Dedique estos dias a experimentar con el receptor VLF y la bambú-aluminio antena. Los dias previos habia ensamblado y soldado el receptor [http://www.auroralchorus.com/bbb4rx3.htm BBB4 Bares Bones Basic Natural Radio], un circuito clásico diseñado por Stephen P. McGreevy y fácil para empezar en este ámbito de la escucha VLF (0.1 a 15 KHz), y construido la antena estilo whip de 2 metros de aluminio ensamblada en una caña de bambu de 5 metros. Los resultaros fuerón bastante satisfactorios.&lt;br /&gt;
&lt;br /&gt;
Un receptor VLF nos permite escuchar fenómenos electromágneticos ligados al campo magnético terrestre &amp;quot;magnetosfera&amp;quot;; como descargas eléctricas a muchos kilometros de distancia, impulsos electromágneticos, y particulas que provienen del cosmos colisionando con la atmosfera. &lt;br /&gt;
&lt;br /&gt;
Durante esos dias en Fumaça localizé diferentes lugares en el entorno natural con una especial fluctuación magnética y realize una serie de grabaciones sonoras con las que posteriormente realize una serie de tracks. Por un lado grababa el sonido ambiente del lugar y por otro la transducción sonora que hace el receptor VLF del campo magnético. Posteriormente en la edición mezclo de diferentes formas estas dos capas del paisaje. Las grabaciones no estan procesadas con ningún efecto. A pesar de estar en un entorno bastante aislado era casi imposible no escuchar los 60Hz del tendido eléctrico, eso si con pequeñas variaciones según el lugar.Cada track corresponde a uno de los lugares. También hay material que proviene de utilizar los vegetales, el cuerpo, minerales como antena para el receptor VLF, sobre todo en la track 03 y 04. una forma de cortocircutar el dispositivo produciendo  una serie de feedbacks.&lt;br /&gt;
&lt;br /&gt;
'''Los lugares fueron''' &lt;br /&gt;
&lt;br /&gt;
'''01''' cerca de una marca de un punto de intensidad magnética al lado de la casa, hecha por Anaïse con una piedra de cuarzo. &lt;br /&gt;

&lt;br /&gt;
'''02''' uno de los monticulos más altos en el paisaje próximo, donde vacas salvajes subén a pastar, un camino en espiral te lleva a la cumbre. &lt;br /&gt;

&lt;br /&gt;
&lt;br /&gt;
'''04''' zona posterior más alta, el sitio más alejado de la casa y con otro microclima y vegetación, sin casi sonido de 60Hz del tendido eléctrico&lt;br /&gt;

'''05''' en la zona superior de  una cachoeira o cascada cerca del lugar con una  caida de 100 metros&lt;br /&gt;
