Beethoven: Symphony No.3 in E♭ major, op.55, “Eroica” — comparing recordings with the following artists: Bernstein/New York Philharmonic (1964), Bernstein/Vienna Philharmonic (1978), Böhm (1972), Dausgaard (2006), Furtwängler/Vienna Philharmonic (1948), Furtwängler/Berlin Philharmonic (1952), Hogwood (1985), Kleiber/Concertgebouw (1950), Klemperer (1959), Norrington/RSO Stuttgart (2002), Toscanini (1953), Walter/New York Philharmonic (1941 & 1949), Walter/Columbia Symphony Orchestra (1961), Zinman (1998)
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.
