One underwater recording from the Amazon river (Brasil) in 2011. The pulses are made by several unknown underwater insects. To listen to these pulses the recording is slowed down one hundred times. All sounds and possible distortions are intentional. The result of the reproduction depends of the sound equipment.
One copy of blue mini-cd self-published (2015)
