Pipistrelle. Attracting bats (2012)

Sound performance. Electronics and bat detector. 
Gargonza, Italy, 2012. Electronics and Viola (Ulrich Mertin).

Trying to attract bats with ultra-sonic sounds and little stones being thrown in the air.
The sounds of the approaching bats were being made audible through a bat detector.

Trying to attract nightingales with imitations of bird chant on a viola, too.
