. . . I love Berg's Violin Concerto, incidentally! I could never make head of tail of Schönberg's, however, until I heard it in the revelatory recording by Hilary Hahn, after listening to which I had the temerity to take the grave risk of declaring to the distinguished Schönberg scholar Malcolm MacDonald that she plays it as though it's a piece of music...
I've unearthed broadcasts of a) Adès's and b) Birtwistle's, but have no idea whether either of them is serial. (In fact Adès sounds like Puccini warmed up.) Do those interest you?
