The Sandro Materassi ensemble has been named after the celebrated violinist and teacher under whose guidance both the violinists of the ensemble studied. The quartet was founded in 1991 and made its début at Spoleto Festival in 1992. Since then it started a brilliant career, with regular appearances in the most renowned Italian concert societies (Rome, Florence, Milan, Palermo, etc.) and in Switzerland and South America.

Alberto Bologni (b. Prato, 9th december 1963), studied under the guidance of Sandro Materassi and graduated with full honour at Conservatorio Luigi Cherubini di Firenze. Later he studied with Stefan Gheorghiu and Ilja Grubert, taking the soloist degree at Rotterdams Conservatorium. He also studied quartet with Piero Farulli at Accademia Chigiana di Siena. He was prize winner at Viotti and Spohr Competitions.

Mr. Bologni began his career in 1979, after being awarded the Leonardo da Vinci prize in Florence. He played in duo with the pianist Giuseppe Bruno or as leader of Sandro Materassi string quartet and piano quintet in the most important concert halls and theatres in Italy, Germany, Switzerland, England and Venezuela (Carlo Felice di Genova, Pergola di Firenze, St. John Smith Square Hall in London, Gasteig and Herkulessaal in München, Manzoni di Milano, Caio Melisso di Spoleto Università di Roma, Bellini di Catania etc. etc.). As a soloist he played with such conductors as Bellugi, Bruggen, Dumbraveanu, Harrap, Maschat, Mihaescu, Pinzauti etc. He has been the leading concertmaster since its foundation of Camerata Strumentale Città di Prato, considered one of the best Italian chamber orchestras now operating.

Alberto Bologni recorded CD's for the labels such as Diapason, Arts, Tactus, Cristophorus and through the Materassi ensemble with Radio Svizzera Italiana and Radio Suisse Romande.


Danilo Rossi graduated with full distinction in 1985 with and then completed and perfected his studies with Dino Asciolla, Piero Farulli and Yuri Bashmet. At only 20 years-old he was chosen by Riccardo Muti to fulfill the role of first viola solisoist of both the theatrical and philarmonic orchestras of la Scala, so becoming the youngest ever first violista in the history of this world-famous and prestigious Opera House. It is this role in which we still find him.

Danilo Rossi has won many national and international competitions (including those of Vittorio Veneto, Stresa and Moscow) and was awarded with the Honorary Diploma from the Accademy of Chigiana. He is regularly invited to perform in the major international festival with musicians of the calibre (calibro) of Azzolini, Brandis, Baschmet, Brunello, Canino, Carmignola, Chung, Gallois, Gerart, Ghiglia, Lucchesini, Muti, Tortelier and many others.

Within the theatre, he worked with important actors such as Alessandro Baricco, Stefano Benni, Ascanio Celestini, Licia Maglietta, Marco Paolini and Daniela Piccari.

Danilo Rossi registered for Nuova Era, Fonit Cetra, Agorà, Tymallus and Sony. In 1999 EMI released a CD with the recording of Mozart Sinfonia Concertante with the Philarmonic of la Scala, conducted by Riccardo Muti.

Danilo Rossi is also a devoted teacher and holds master classes at the most prestigious Academies.


Such an excellent performance makes us rejoice for the meeting of four so skilled and sophisticated musicians as the ones forming the Sandro Materassi string quartet.

Alberto Batisti (La repubblica)


At the end of the concert the audience had the sensation to have witnessed a memorable event.

Leonardo Pinzauti (La Nazione)


Excellent intonation, excellent technique, a sound at the same time clear and dense.

Andrea Ambiveri (La Libertà, 1993)


In a sold-out St. Clemens Church the audience could hear a concert that would stay for a long time in their memory. The breathtaking solo's were perfectly performed and the audience was drawn by the peculiar timbre of the Russian songs. When the last song of the choir: "I adore the love of God" was finished, you could see that the eyes of many were wet with tears.

Dithmarscher Landeszeitung


Very few times we have had the oppurtunity to listen to such a breathtaking and creative interpretaion of a masterpiece of our days [Ligeti’s String quartet #1].

Leonardo Pinzauti (La Nazione)


The Sandro Materassi string quartet has a perfect melted sonority.

Elisabetta Torselli (L’Unità)
