Trío Arte
was founded in 1981 at the initiative of Juana Subercaseaux, then director of the Institute of Music of the Pontificia Universidad Católica. The formation of this ensemble included María Iris Radrigán on piano, who arrived in Chile in 1980 after studying in Germany with the idea of forming a trio, motivated by the versatility of this formation. Sergio Prieto, who also returned from studying in Europe and joined the teaching staff of the Instituto de Música, joined on violin. Initially, Arnaldo Fuentes took on the role of cellist, but after three months of work, and with the arrival of Edgar Fischer from Switzerland to establish himself as a teacher at the Institute, what would become known as the definitive Trio Arte was formed. Already as part of the teaching staff of the Instituto de Música UC, Radrigán, Fischer and Prieto perform their first concert in the Sala Arrau of the Teatro Municipal, with excellent results. Their first tour, supported by the Instituto de Música, includes multiple regions of Chile, including educational activities such as master classes. In 1982, the Trio made its first international tour to Brazil and in 1983 and 1984, they embarked on their first tour outside Latin America to Europe and the United States.

During this tour they have the opportunity to record concerts for the BBC in London, Swiss TV, Radio Nacional de España and the Swiss label Gallo, as well as performing live at important venues such as Carnegie Hall (New York) and Wigmore Hall (London), among others. After such performances they received excellent reviews in international newspapers such as the New York Times and the Daily Telegraph, which highlighted their "musical intelligence and artistic sensitivity" and described them as "solid musicians with excellent technique".

Although the strong point of the Trio Arte are the works of European composers from the 18th to the 20th centuries, such as Beethoven, Mozart, Brahms, Schumann and Shostakovich, among others, on various occasions they perform contemporary Latin American works. The ensemble's international and Chilean recognition after years of improvement has attracted the attention of various national composers, who compose works to be performed by the ensemble. Some of the most outstanding compositions include Alejandro Guarello's Trio 1982, whose world premiere is performed during the Trio's tour to the United States, as well as works by Celso Garrido-Lecca, Francesca Ancarolla, Federico Heinlein, among others.

The discipline of Radrigán, Fischer and Prieto was one of the most outstanding qualities of the Trio, who constantly worked to improve both individually and in the musical performance as a whole. The Trio constantly worked to improve, both individually and as a group, and frequently took part in advanced training activities with outstanding international musicians such as the pianist Menahem Pressler, who, according to the members themselves, was a fundamental guide for the development of the ensemble. Also noteworthy was the meeting with the Beaux Arts ensemble during their visit to Chile, who listened to the Trio Arte and highlighted them as one of the most important chamber music trios of that time.

TranslatedDuring the nineties, with Sergio Prieto's assignment as concertmaster of the Orquesta Sinfónica de Valles de Barcelona, a situation that made it impossible for the violinist to participate actively in the Trio's concerts, a new generation of violinists linked to the Instituto de Música de la Pontificia Universidad Católica had the opportunity to participate sporadically as part of the ensemble, among them Alonso Fernández and Rubén Sierra.

With Prieto's return to Chile, the Trio Arte can continue its activities, although less frequently than before. Also, Radrigán and Fischer devoted themselves in parallel to the Fischer-Radrigán Duo and to teaching at the Catholic University, which, added to Prieto's musical and teaching activity, made time for trio work scarce. Gradually, the activities of the ensemble became more and more spaced out over time, until 2009, when they ceased their activities completely.

The legacy of the Trio Arte is not restricted to its numerous concerts and recordings, but also includes its pedagogical work, not only as part of the teaching staff of the Institute of Music of the Pontificia Universidad Católica, but also in numerous master classes and courses given in Switzerland, Spain, Peru and many regions of Chile, the teaching aspect being perhaps one of its most relevant legacies.
