Guitar Quartet

Grammy-winner Jason Vieaux, “among the elite of today’s classical guitarists” (Gramophone), is described by NPR as “perhaps the most precise and soulful classical guitarist of his generation”. In appearances from New York’s Lincoln Center to Amsterdam’s Concertgebouw and the Seoul Arts Center, Jason Vieaux has cemented his reputation as an artist of brilliance and uncompromised mastery.  

Vieaux’s extensive discography includes his “Bach Volume 2: Works for Violin” released on Azica in 2022 to rave reviews for his “eloquent and vibrant performances” (Gramophone). Additional 2022 releases include “Shining Night” featuring his duo with acclaimed violinist Anne Akiko Meyers (Avie Records) and Michael Fine’s “Concierto del Luna” with flutist Alexa Still (Sony Classical), both enjoying strong critical acclaim. Vieaux recorded Pat Metheny’s “Four Paths of Light”, a solo work dedicated to him by Pat, for Metheny’s 2021 album “Road to the Sun”. Jason Vieaux won the 2014 Best Instrumental Classical Solo Grammy Award for Play. The Huffington Post declared Play is “part of the revitalized interest in the classical guitar”. 

A busy touring performer, Jason Vieaux enjoys repeated invitations from distinguished series, including San Francisco Performances, Chamber Music Society of Lincoln Center, Philadelphia Chamber Music Society, and the 92nd Street Y, among others. Festival engagements include Ravinia, Caramoor, Domaine-Forget, Music@Menlo, Round Top, and the Eastern Music Festival. Overseas performance venues include Amsterdam’s Concertgebouw, Seoul Arts Center, Shanghai Concert Hall, Sala Sao Paolo, and Teatro Colon in Buenos Aires. 

In 2011 Vieaux co-founded the guitar department at the Curtis Institute of Music (with David Starobin). He has taught at the Cleveland Institute of Music for 25 years. Jason’s online Guitar School for Artistworks Inc. has hundreds of subscribers from all over the world. He plays a guitar by Gernot Wagner, 2013.

A violist of international reputation, Roberto Díaz is president and CEO of the Curtis Institute of Music, following in the footsteps of renowned soloist/directors such as Josef Hofmann, Efrem Zimbalist, and Rudolf Serkin. As a teacher of viola at Curtis and former principal viola of the Philadelphia Orchestra, Mr. Díaz has already had a significant impact on American musical life and continues to do so in his dual roles as performer and educator.

As a soloist, Mr. Díaz collaborates with leading conductors of our time on stages throughout North and South America, Europe, and Asia.  He has also worked directly with important 20th- and 21st-century composers, including Krzysztof Penderecki—whose viola concerto he has performed many times with the composer on the podium and whose double concerto he premiered in the United States—as well as Edison Denisov, Jennifer Higdon, Ricardo Lorenz, and Roberto Sierra. His recording of Jennifer Higdon’s Viola Concerto won the Grammy for Best Contemporary Classical Composition in 2018.

As a frequent recitalist, Mr. Díaz enjoys collaborating with young pianists, bringing a fresh approach to the repertoire and providing invaluable opportunities to artists at the beginnings of their careers. In addition to performing with major string quartets and pianists in chamber music series and festivals worldwide, Mr. Díaz has toured Europe, Asia, and the Americas as a member of the Díaz Trio with violinist Andrés Cárdenes and cellist Andrés Díaz. The Díaz Trio has recorded for the Artek and Dorian labels.

Mr. Díaz’s recordings on the Naxos label with pianist Robert Koenig include the complete works for viola and piano by Henri Vieuxtemps and a Grammy-nominated disc of viola transcriptions by William Primrose. Also on Naxos are Brahms sonatas with pianist Jeremy Denk and Jonathan Leshnoff’s Double Concerto with violinist Charles Wetherbee and the Iris Chamber Orchestra led by Michael Stern. Mr. Díaz’s live performance of Jacob Druckman’s Viola Concerto with Wolfgang Sawallisch and the Philadelphia Orchestra is available on New World Records. He has also recorded the Walton Viola Concerto with William Boughton and the New Haven Symphony for Nimbus Records, and works for viola and orchestra by Peter Lieberson with Scott Yoo and the Odense Symphony Orchestra and for Bridge Records.

Since founding Curtis on Tour in 2007, Mr. Díaz has taken this successful initiative to North and South America, Europe, and Asia, performing chamber music side-by-side with Curtis students and other faculty and alumni of the school. His tenure as president of Curtis has also seen the construction of a significant new building which doubled the size of the school’s campus; the introduction of a classical guitar department and new conducting and string quartet programs; and the launch of Curtis Summerfest, summer courses open to the public. In the fall of 2013 Curtis became the first classical music conservatory to offer free online classes through Coursera.

Also under Mr. Díaz’s leadership, Curtis has developed lasting collaborations with other music and arts institutions in Philadelphia and throughout the world and established a dynamic social entrepreneurship curriculum, supported by a prestigious Advancement Grant from The Pew Center for Arts & Heritage. Designed to develop the entrepreneurial and advocacy skills of young musicians, this curriculum includes the project-based Community Artist Program (CAP) and the post-graduate Community Artist Fellowship program, which gives recent Curtis graduates the opportunity to dedicate a year of arts-based service to the community.

Mr. Díaz received an honorary doctorate from Bowdoin College and was awarded an honorary membership by the National Board of the American Viola Society. In 2013 he became a member of the prestigious American Philosophical Society founded by Benjamin Franklin. As a member of the Philadelphia Orchestra, he was selected by then-music director Christoph Eschenbach to receive the C. Hartman Kuhn Award, given annually to “the member of the Philadelphia Orchestra who has shown ability and enterprise of such character as to enhance the standards and the reputation of the Philadelphia Orchestra.” He received a bachelor’s degree from the New England Conservatory of Music, where he studied with Burton Fine; and a diploma from the Curtis Institute of Music, where his teacher was his predecessor at the Philadelphia Orchestra, Joseph de Pasquale. Mr. Díaz also holds a degree in industrial design.

In addition to his decade-long tenure as principal viola of the Philadelphia Orchestra, where he performed the entire standard viola concerto repertoire and gave a number of Philadelphia Orchestra premieres, Mr.  Díaz was principal viola of the National Symphony under Mstislav Rostropovich, a member of the Boston Symphony under Seiji Ozawa, and a member of the Minnesota Orchestra under Sir Neville Marriner. He plays the ex-Primrose Amati viola.
