Bacewicz on Dodecaphony

I came across this statement about dodecaphonic music from Grazyna Bacewicz.

For me the work of composing is like sculpting a stone, not like transmitting the sounds of imagination or inspiration. The majority of contemporary composers work as systematically as bureaucrats. If there is no inspiration one does the menial "workshop" jobs, if there is inspiration the creative work continues. Discipline, strict discipline in composition is essential to for me. There is a saying: the house will fall down if it were to be built without principles. However, since dodecaphony does not appeal to me very much I am sitting alone and working out my own system.

[Letter of Grażyna Bacewicz to her brother, Witold (Vytautas Bacevicius), 23 October 1958].

I also came across this photo on the above website. Bacewicz is sitting on a Jury in Moscow in 1960. I recognize Leonid Kogan, so I imagine that it was a violin competition. Since there are flags from around the world, I imagine it was an international violin competition.

Update: [Here is a link to learn the other members of the jury.]
