Most beautiful violin recording you have heard

On beauty alone, Brahms Double Concerto -- Oistrakh , Rostropovich, Szell.

For Gregm on emphasizing the beauty of the pieces, Milstein and Sitkovetsky, Bach Sonatas and Partitas. I would also check out Fritz Kreisler, the recent transfers are decent and he certainly emphasized beauty of tone. The reference perfomance of the Sibelius is the 1935 Heifitz with Beecham and the London Philharmonic.
