Some time ago, a friend send me a copy of extremely rare Heifetz's
recordings of a Mozart's sonata and Beethoven Spring played as an very
bad violin student on purpose, out of tune, plain, almost without vibrato
and boring; but as a complement, the one and only recording of Joseph
Hauge violin sonata, with composer at the piano. Do you know those
recordings?
