Tim Mangan of the Orange County Register lists ten recordings of works that serve as a newby's introduction to musical Modernism. It's a fine list, and I won't spoil it for you by reprinting it here.
In a his comment on a piece that interpolates sketches from a 19th century composer's music with the 20th century composer's original music, Mr. Mangan describes the original music as "atonal but exquisitely so". This is really picky, I know, but I wish he had not phrased it that way, unless of course he generally finds atonality less than exquisite. (The rest of the article doesn't read that way.)
I would rather have seen "exquisitely atonal" or "atonal, and exquisitely so". Again, I'm being picky, but I think it's better if we don't use negatively charged language in our attempts to promote our music.
