Shortly after Barack Obama was sworn in as President, the Los Angeles Times music critic Mark Swed offered a list of "rich, wise, inclusive original voices" he might invite to the White House to signal his commitment to the arts. Others have even suggested the appointment of an arts czar.

"[T]he one and only way to interest people in classical music is to get them to play it as children," Adams asserts. "I think people should just be exposed all the time to great art. That sounds like a really simple, grandiose statement, but I think it's really true."
