Olhon is a duo from Italy formed by Massimo Magrini (Bad Sector) and Zairo (Where). Their collaboration started in 2001. Its sound mainly consists in field recordings made in special, and often extreme locations (underwater, inside deep caves, etc.), carefully processed and structured by both members. The goal is producing a "listenable" musical product keeping a strong relation with the original, conceptual field recording. No artificial sound sources (HW or SW synthesizers) are used in the final mixing.
