I saw this thing yesterday afternoon, and it had clips of people like Oistrakh, Kreisler, Heifetz, Stern, and so on performing. Awesome stuff. Of all the guys on that little instrument David Oistrakh was my favorite. At first hearing I'm not sure exactly why yet, but I want to say it's because his playing is very rich and full...you get the whole violin rather than just the top end from this guy. And he didn't display that really fast, hectic vibrato I have difficulty enjoying. I'm sure there's a whole lot more to this guy than just this, even if what I say can't be defended. There were also little parts in the documentary where things like tuning were discussed, how some players would play a particular note flat to bring notice to it. Neat. And of course the bowings used to execute all that stuff were amazing. It all made the bass seem much bigger when I went back to it to work scales that evening and appreciative that even if we never get to do some of the things those violinists do, we can still work our instrument to make them sound their best.
