Heifetz, Milstein, Menuhin....but they would need to practice a lot with each other a lot first since I only know their solo works mostly.
Actually there are too many other names that come to mind honestly too....perlman, grumiaux, oistrakh etc....or maybe the ethereal Don Bradman of all Violin players Paganini? In fact I would just like to hear Paganini by himself to be honest, just to see what the big fuss is about hehe
For more recent, I would love to see the ladies Hahn, Fischer, Chang...or steinbacher for both audio and visual stimulation
