The definition of high art has been passed down from Europe's classical age. High art was that made by serious, trained minds for appreciation by the noble classes. This was in contrast to popular art, "popular" then having a negative connotation.
Since that time, the industrial revolution has caused the unprecedented growth of the middle class (and democracy). The monetary potential for mass media began to attract talented individuals as an increasingly educated population demanded increasingly intelligent media. Popular art quickly came to aspire to high art, first with Duke Ellington in jazz and the Beatles in rock and roll. Motifs were developed, tonality was explored, lyrics with complex ambiguity were written and records became thematic opuses.
Meanwhile, classical music became increasingly academic. The nineteenth century trends of adding instruments and dissonance were carried on toward their natural conclusions during the twentieth century, ensuring that high art continued to be out of reach for a majority of the middle class. This formed the avant-garde of modern art.
Popular music continued to pick up innovations from the high art community, with avant-garde movements springing up in both jazz and rock. Yet the stigma of popular music continues. I won't forget my music professor describing Radiohead as his favorite "pop music"; that qualification being contrasted with "serious music", a pejorative shockingly ubiquitous among composer-academics.
While the many breakthroughs of the avant-garde movement cannot be denied, a cursory listen reveals that it has ceased to resemble classical high art. A legacy of elitism has combined with a philosophy of progress to make it an unwieldy animal. Modern composition has sufficiently lost its way that I predict it will fail to attain classic status. Instead, the music of the middle class will lay down the impressive legacy of America and the twentieth century.
KDVS has taken a different route in its treatment of twentieth century music, finding its own elitism in the underground. KDVS DJs hold a consensus that true art comes from the soul rather than from monetary incentive. They call music made for self-gratification and little or no money "folk", and there are few greater complements within the station than to call an artist folk. Consider this though, think of your favorite artists and count how many of them did it for money. Bach, Miles Davis, Bob Dylan, The Velvet Underground, Led Zeppelin, the Sex Pistols, Sonic Youth, Metallica, Beck, etc. Now count how many didn't.
Partly, this is because it takes money to pay for art education, equipment, production and distribution. Partly it's because these are extremely talented people working hard who expect to be compensated accordingly. Personally, I think we should applaud those who refuse to compromise their artistic ideals for money, but I think we should applaud still more those who can have their cake and eat it too. Self-gratification is always a slippery slope and money provides for better treatment of music.
