The soundtracks of Peter Jackson 's films "The Lord of the Rings" and "The Hobbit" - based on J.R.R. Tolkien 's work - will be performed "live" by a symphony orchestra, a choir and some soloists. All fans of the "Middle World" will thus be able to relive in two hours, together with some famous guests, the dark atmospheres of Mordor, the attack of the black knights, the lyrical melodies of the elves and other moments of the saga.
