Most underrated composer of 20th Century?

"Easy, I bet 9 out of 10 people would just proclaim it nonsense out of hand."

9 out of 10 people are NOT geniuses. :^)

I would tend to agree with the pack on this one for the most part.

Bach is pretty minimalist compared to most that followed. I'd say that's the standard for simplistic quality to compare with.

With regard to the ultimate merits of minimalist music (tho without any suggestion of equivalency and - further - without any personal judgement one way or the other):

I wonder what kind of critique this crew would have provided after the premier of Rite of Spring.

I would have thought it bombastic, if this was about overated Stravinsky would be on my short list.

Dayglow, you certainly can make a strong case for Bax alright !!

Not terribly surprising. Your list of overrated music would likely be far more interesting to me than your list of underrated music. But personal preferences differ, I guess, and thus the world continues to go 'round.
