The violins, violas and cellos played by the Orchestra of the Sea in its debut performance at Milan’s famed Teatro alla Scala carry with them tales of desperation and redemption. The wood that was bent, chiseled and gouged to form the instruments was recovered from dilapidated smugglers’ boats that brought migrants to Italy’s shores; the luthiers who created them are inmates in Italy’s largest prison.

The project, dubbed Metamorphosis, focuses on transforming what otherwise might be discarded into something of value to society: rotten wood into fine instruments, inmates into craftsmen, all under the principle of rehabilitation. Two inmates were granted leave to see the Orchestra of the Sea's debut concert Monday featuring 14 prison-made stringed instruments playing a program that included works by Bach and Vivaldi.
