Carl Ruggles was a crazyass American who died in his 90's in early 1970's. He managed to get rich selling his paintings. He was a very dark cynical bastard and a brutal vulgarian. He hated everybody except for Ives. He called Charlie Parker a worthless n*gger and described Schoenberg as a shallow k*ke who should've moved to Treblinka. Ives defended his music vigorously. When Ruggles' music was booed for its dissonance he berated the audience to appreciate "masculine" music and to one fellow to "use his goddamn ears like a man".
Here's one of his paintings:
