Thanks for posting Sara Fishko's insightful and historically-informed talk over WNYC about the first recording of the Sibelius Violin Concerto. That one with Heifetz and Beecham conducting the London Philharmonic is also my favorite performance. There's something about Heifetz's tight ongoing vibrato that makes me believe that his violin isn't a constructed instrument but a singing human voice. In the First Movement, "Allegro Moderato", those double stops, in their first appearance, six bars after rehearsal number 10 in the full score, never fail to move me to tears of wonderment and joy, so intense are they. The same is true of the "Adagio di molto" movement all the way through; and the insouciance and devil-may-care feeling I get from hearing the "Allegro" movement is something rather indescribable. Interesting that Ms. Fishko also mentioned the first recording of extracts from "Porgy and Bess" for Victor by Lawrence Tibbett, Helen Jepson and an Orchestra conducted by Alexander Smallens. The original 78's state under the credits that the recording was supervised by George Gershwin.
