Jonathan Biss, following the December concert in his Beethoven Piano Sonata Cycle, is joined by Antoine Lederlin and Krzysztof Chorzelski of the Belcea Quartet (who are currently performing the complete Beethoven String Quartets) for a discussion on their programmes. The conversation includes comparisons between the string quartets and piano sonatas, the co-existence of contrasting elements - human & superhuman, complex & banal - in the works, and what it's like performing a complete cycle by one composer ("living with" Beethoven).
