All just my personal opinion
Concert review, Claire Huangci, Heiko Mathias Förster / Prague Royal Philharmonic @ Zurich, 2018-10-20 — Works by Ludwig van Beethoven: Overture “Leonore” No.3 in C major, op.72b / Piano Concerto No.5 in E♭ major, op.73, “Emperor” / Symphony No.6 in F major, op.68, “Pastorale”
Concert review, Aleksandr Shaikin, Anastasia Kobekina, Heiko Mathias Förster / Zürcher Symphoniker @ Tonhalle Maag, Zurich, 2018-07-02 — Mendelssohn: Overture “A Midsummer Night’s Dream”, op.21; Chopin: Piano Concerto No.2 in F minor, op.21; Schumann: Cello Concerto in A minor, op.129; Beethoven: Symphony No.8 in F major, op.93
With the entrance of the solo violin, though, the attention turned towards Sophia Jaffé, who presented herself as an experienced, expressive violinist, with a sonorous, full tone, delivering a solid, convincing interpretation.
