Question about classical music:

For classical music, should I...

(a) List only classical recordings released in the 1970s (probably won't bother with this because it seems too arbitrary to me)
(b) List only classical pieces composed/premiered in the 1970s (i.e. the date that you get if you visit a composition's wiki page)
(c) List only classical CDs which unambiguously meet both criteria, e.g. Philip Glass' North Star

?

Genius is a rare commodity in any art form, but at the end of the 20th century it seemed all but non-existent in jazz, a music that had ceased looking ahead and begun swallowing its tail. If it seemed like the music had run out of ideas, it might be because Anthony Braxton covered just about every conceivable area of creativity during the course of his extraordinary career. The multi-reedist/composer might very well be jazz's last bona fide genius.

Braxton has produced many excellent recordings through the years, but only a small number stand out from the pack the way this one does. This version of his pianoless quartet is captured live in an inspired, energized performance at the first Dortmund Jazz Festival in Germany. Trombonist George Lewis had only recently joined the group, replacing the more introspective trumpeter Kenny Wheeler. Braxton's compositions are uniformly brilliant, incorporating marching band themes, lightening-fast hard bop-influenced runs, and strings of non-syncopated eighth notes, all of which contribute to a sense of wonder and excitement. Also, Braxton is in marvelous form on his varied horns, springing forth an arsenal of seemingly endless ideas.

btw, was just listening to arvo part's "tabula rasa" this morning... it is surely making my list...

It's 1984.

One thing that's not clear from the first post: are these lists supposed to be ranked or unranked?
