Most underrated composer of 20th Century?

Lesarsfool, actually, Andy didn't have to draw those over and over. He just picked a photo or drew the image once, had a photo film made, and then had had his studio assistants make silkscreens. Those were then able to be screen printed as fast as he could tell his studio assistants how to mix the ink. So I'm not so sure he had to work harder than Glass ;-)

Arguing the merits of minimalism (both visual and musical) is a zero sum game, no one ever convincingly gains the upper hand. So, how can we reduce the elements of a worthwhile aesthetic experience to the minimum without becoming so reductive that the experience is without meaning?

Exactly Frogman and Mapman, it's so hard to get a grip on what "underrated" means. My musically well educated colleagues roll their eyes with ennui at the mention of most composer's that the average classical listener has never heard of, so it is all relative. Plus, I agree with earlier statements about cultural prejudices coming into play. I happen to really like Takemitsu & Minoru Miki, but they don't seem to resonate with a large number in the western world. Also like Rautavaara, Lindberg, Kokkonen, and Saariaho, but general appreciation for Scandanavian composers ends with Sibelius and Grieg. Then there are "could have been greats" like Gideon Klein whose life was cut short by a Nazi concentration camp and Karl Amadeus Hartmann whose composing career was pressured by his duties as an administrator resurrecting German musical culture after WWII. Paul Hindemith deserves a place at the table of underrated greats as well IMO.

Thanks for chiming in on that bit of critical "flat earth thinking" regarding Stravinsky Learsfool. To suggest Stravinsky lacks a place among the highest echelon of composers leaves me flabbergasted. Send me to the proverbial desert island, give me daily does of Bach and Stravinsky, and I would suffer little.
