I have question. I've always wondered "why serial"? That is, I can see why composers in the early C20 would have thought composing totally chromatically, but where did the idea of doing it serially come from, after all there were never any tonal, serial compositions.
Over to our apologists for serialism for an answer, I think??
Well, don't anyone look to me to provide one! - but, while wondering to whom else to put that question, I don't think that Berg's Violin Concerto's the only tonal serial work...
