Frances-Marie Uitti, dedicatee of all Scelsi's cello works, collaborated intensively with him for over 10 years editing and then recording La Trilogia, a massive 3 part work of 45 minutes in length which Morton Feldman called his "autobiography in sound". It was first premiered in Festival di Como, and recorded on Fore records (Raretone) with Scelsi in the studio and later for Etcetera Records. A more recent acclaimed version with several of the Latin Prayers is to be found on ECM under the title Natura Renovatur.
