The third movement, the serenade (starting at 2m09s in this extract), is on the Grade 8 viola syllabus. Performed by Yuri Bashmet.
Performed by Nigel Kennedy. Movement three, starting at 5m14s, is on the Grade 8 syllabus.
I sometimes get asked, "Whatever happened to Nigel Kennedy?" Well, he's still very much around, playing a lot of jazz and klezmer music, as well as classical performances. However, he now lives in Poland and rarely performs in the UK, which maybe is why it's sometimes assumed that he just disappeared! The second video, however, proves that he's very much alive and playing.
