From Grotta Sonora:
"Grotta Sonora is a project for the design and construction of hand-crafted experimental musical instruments. Madhava Carrara and Margherita Cioffi, artisans and musicians, started this project building on their personal experimentation with sound, using different types of metals.
Madhava Carrara is a musician, percussionist and artisan who was brought up in an environment strongly influenced by the Indian culture. He has been experimenting for years with the craft of making stringed, wind and percussion musical instruments, using a wide range of materials, including recycled waste materials. With Margherita Cioffi, singer and decorator, he started the exploration that is at the foundation of this project.
Their first instruments were crafted in a cave (“grotta”) of Etruscan origin close to Calcata, an ancient village in the Treja Valley. The cave eventually turned out to be the perfect place to play these newly-crafted instruments, thus kicking off the Grotta Sonora project.“
