Glazunov violin concerto -- Suggestions?

There is a version on Naxos which have generally excellent
sound.

You can't go wrong w/Heifetz & Hendl on RCA - on CD you could also get an outstanding Sibelius VC as well depending on which CD you get, there are multiple releases w/different partnering pieces. If you want something new, and you want to explore his symphonies you might enjoy Polyansky's on Chandos which includes the VC and the 1st Symphony. I have really enjoyed Polyansky's Glazunov's Symphonies #'s 1 thru 5 on Chandos.
