Today, Pyotr Tchaikovsky's Violin Concerto ... with Nathan Milstein on the violin and Walter Hendl conducting the Chicago Symphony Orchestra. I believe this is a recording from 1963.

From Wikipedia:

The Violin Concerto in D major, Op. 35, written by Pyotr Ilyich Tchaikovsky in 1878, is one of the best known of all violin concertos. It is also considered to be among the most technically difficult works for violin.
