The practice of attempting to record ghosts is called Electronic Voice Phenomena (EVP). The sounds that make up EVP are apparently sonic events of unknown origin, which can be heard, and sometimes captured in recordings, on various types of electronic apparatus, including tape recorders and even radio equipment. The voices on the tapes take on diverse forms, sometimes seeming to speak in tongues, singing or speaking in gibberish. The messages often make a sort of backward sense as though communication is difficult. They can also apparently call by name and speak directly to researchers. They can be heard over telephones and as anomalous interference on tape recordings. Some of them seen to enjoy engaging in dialogue, answering questions or supplying personal information about the researchers, possibly as a way of achieving credibility.This album is a new experiment by Daniele Santini, who mixes music and EVP recordings in a respectful way towards this phenomenon, whatever its origin.
