Alfredo Perl
PianoAlfredo Perl has established himself as one of today’s leading pianists. Chilean by birth, he studied with Carlos Botto in Santiago, Günter Ludwig in Cologne and Maria Curcio in London. Since his first public performance at the age of nine, he has given numerous concerts throughout the world and has been a prize-winner at major competitions.
Perl performed a complete Beethoven Sonatas cycle at London’s Wigmore Hall, as well as in Santiago and Moscow, to huge public critical acclaim. The completion of the Wigmore Hall series coincided with the release of his Beethoven Sonata cycle with the Diabelli Variations. Perl has been said to play Beethoven "with sparkling freshness, extraordinary tenderness and unaffected brilliance. He demonstrates that, even in these prosaic times, the great tradition of Beethoven playing lives on." (Joachim Kaiser, Süddeutsche Zeitung). He has also recorded works for solo piano and for piano and orchestra by Franz Liszt, Schubert sonatas and the complete works of Ravel. The BBC label Opus Arte issued a DVD of his recording of Chopin Preludes op. 28.
Alfredo Perl made his debut in the International Piano Series at the Queen Elizabeth Hall in 1992 (a series to which he returned to several times), which was closely followed by his first recital at the Wigmore Hall. Perl has performed worldwide at major venues such as the Vienna Musikverein and Konzerthaus, London’s Barbican Centre, Rudolfinum Prague, Munich’s Herkulessaal, the Cologne Philharmonie, Izumi Hall Osaka, Teatro Colón in Buenos Aires, Sydney Town Hall and Opera House and the Great Hall of the Moscow Conservatoire. He has also visited the Schwetzingen, Schleswig Holstein Musik, Rheingau, Bad Kissingen, and Bonn Beethovenfest festivals; the Bath International Music Festival; Harrogate Festival; Beirut Al Bustan Festival and the Haydn Festival in Eisenstadt.
A remarkably versatile performer, Perl has performed with orchestras such as the London Symphony, BBC Symphony and Royal Philharmonic Orchestras, as well as the Hallé, Melbourne Symphony Orchestra and Sydney Symphony. He has also appeared with the Orchestre de la Suisse Romande, Gewandhausorchester Leipzig, Wiener Symphoniker, Netherlands Philharmonic and Tokyo Symphony orchestras.
Alfredo Perl has recently taken up the baton and will be conducting several concerts with the Detmolder Kammerorchester, with whom he holds the position of Music Director.

From 1999 to 2015 Roland Glassl was the violist of the Mandelring Quartet, recognised as one of the foremost quartets in the world with frequent engagements in virtually every major chamber music hall. The quartet’s numerous recordings, which span much of their wide-ranging repertoire, have garnered the German Music Critics’ Prize as well as multiple nominations for the International Classical Music Award.
Teaching has always been an important addition to his concert life for Roland Glassl. From 2004 to 2018, he succeeded Tabea Zimmermann as Professor for Viola at the Frankfurt University of Music and Performing Arts. In 2018 he took over the position of Prof. Hariolf Schlichtig at the University of Music and Performing Arts Munich, returning to his roots.
Roland Glassl was born in Germany, into a luthier's family with a tradition of many generations of violin making. He currently performs on a viola made by his father, who was also his first violin teacher. Later, he continued his studies at the “Musikhochschule München” with Ana Chumachenco. After receiving his artist diploma with distinction, he came to the United States to study violin with Paul Biss and viola with Atar Arad at Indiana University. Fascinated by the deep, warm sound of the viola, he decided to devote himself to the instrument and its music.
