Fyodor Dostoevsky and Giuliano Valdarena in That Awful Mess on Via Merulana which also marks the beginning of his collaboration with the maestro as his assistant director, where several times he  was responsible for the spoken and sung choruses – Prometheus Bound and the Bacchae, the two tragedies that Ronconi directed for I.N.D.A. (Istituto nazionale del dramma antico - National Institute of the Ancient Drama) of Syracuse in 2002 are testimony of his work as assistant director.

However, in the case of the work of Gadda, his contribution, also focused on the drama, allowed him to investigate further the method of Luca Ronconi, and his "maniacal" attention to the text.

This feature, combined with the growing interest in the vocal instrument that pushed him into cyclic phoniatrics studies and to cooperate with Marco Podda, doctor, speech therapist and musician, is a constant of his work as a director, in which he face with the same procedural "humble reading" Shakespeare's texts, the Greek classics or contemporary authors like Edward Bond (Summer), Anita Desai (Notte e nebbia a Bombay, with Omero Antonutti), Amos Oz (Contro il fanatismo, Il monte del cattivo consiglio, Terra di confine) Paul Auster (Città di vetro), Nadine Gordimer (Aggrappati ad un'alba, with Anna Maria Guarnieri), Mario Rigoni Stern (Storie dell'altipiano), Antonio Tarantino (Gramsci a Turi).

However, to the philological rigor and to the sincere and theoretical passion that inspires all his productions, Daniele Salvo responds with a visionary charge that takes inspiration from the modern and surrealist iconographic repertoire and from the cinema of Ingmar Bergman, Andrej Tarkovskij, Orson Welles.

It is particularly evident in the staging of Shakespeare's texts, made for the Globe Theatre in Rome directed by Gigi Proietti, where Daniele Salvo directed, in order, The Tragedy of Julius Caesar (prize Villarosa 2007), King Lear with Ugo Pagliai, Othello and The Tempest, with Giorgio Albertazzi in the role of Prospero. In this regard, Mr. Albertazzi said that Daniele Salvo "among all the directors I've worked on lately, he is the one closest to my spirit."

The bond between Daniele Salvo and Giorgio Albertazzi – started in 2009 with Oedipus at Colonus by Sophocles for the Greek Theatre of Syracuse, and continued with Shakespeare thanks to a drama titled Amleto e altre storie (Hamlet and other stories) that invited the audience to a journey through the writing of Shakespeare of Richard III, Julius Caesar, King Lear and Hamlet – is intended to be strengthened with the new edition of Julius Caesar, work in progress for August 2017, again at the Globe Theatre in Rome.

On the side of classical texts, he was able to explore and learn the writing of Sophocles through the staging of Ajax, that I.N.D.A. entrusts him the following year, and Oedipus at Colonus, which earned him the Golden Graal 2012 award for best directed play.  A very complex operation, which pursues the idea of an interpretative truth to achieve with the help of all the means of expression – music, lights, scenes and costumes. And asking the actor to commit himself emotionally.

From this belief, perhaps, it derives his emancipation from the maestro, full of gratitude and yet determined by an expressive figure that can not help but think of the actor as a being crossed by emotions, made of flesh and blood, and of the emotionalism as a language that transcends time.

For Daniele Salvo, the work on the language becomes a job at the service of emotion, towards a recovery of the original relationship “signifier-meaning”: a significant vocality to get even using the euphony, broken voices, out of tune sounds, false cords.

In 2013, he has been chosen by Franco Branciaroli, artistic director of the Teatro Stabile di Brescia, to stage Macelleria Messicana by Enrico Groppali.  The play has as protagonists Elisabetta Pozzi and Paolo Bessegato.

In May 2013 he is also confirmed for the third time by I.N.D.A. of Syracuse which entrusted him with the staging Oedipus the King by Sophocles at the Greek Theatre, with Daniele Pecci, Ugo Pagliai and Laura Marinoni.

The play has such an outcome in popularity and receipts that I.N.D.A. decides to entrust to Daniele Salvo the staging of The Libation Bearers/Eumenides for the prestigious centenary of the institution. The show is staged, with great success, in May 2014, starring Francesco Scianna, Elisabetta Pozzi, Ugo Pagliai, Piera Degli Esposti, Paola Gassman.
