The Brahms concerto is well known for its demands on the solist (I believe that it was declared 'unplayable in public' by its dedicatee) so it needs a virtuoso violinist and yes, this is a virtuoso performance. However, virtuosity must be subservient to musicality and I don't feel that Vengerov is truly sympathetic to the 'inwardness' intrinsic in Brahms's music (often simulatneously with extrovert rhythm and dynamics). This is very much a personal matter, and others will disagree, but if you recognise what I am saying about Brahms, I think you will probably feel the same!
