I'm fairly sure I can. both Arnold and Simpson were more or less tonal (with increasing harmonic instability and focus on other things as they got older, far as I know), which puts a good number of modern symphonists far away from either of them. They also didn't write any "symphonies for chamber ensemble" far as I know (symphonies for brass band are still for potentially large groupings, I think) which puts them both aways away from Ustvolskaya's symphonies...
