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.
Since 2004, Glassl is professor of viola at the at the Musikhochschule Frankfurt as successor of Tabea Zimmermann. 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.
