Is that the living stereo recording with Beethoven's violin concerto too? His technique together with that gut string tone is hard to beat. I have the Heifetz/Piatigorsky concerts along with his living stereo recordings.
It is Mendelssohn's 1st and 2nd, I have both the Beethoven and it on vinyl and when listening in my office I stream both on TIDAL, love the early RCA sound. I like his pace, never a dull moment.
