I've heard wonderful things about the Glass, which intrigues me since I'm not his biggest fan. I'll have to get around to listening to it someday- just after I get through all the other stuff I have to listen to.
As for violin concerto's... Beethoven, Bach Double and Brahms stand as the pinnacle in the genre for me (cliche, I know). But I also really love Elgar, Barber, Shostakovich, Adams and the other Bach concerto's. Tchaikovsky, Sibelius, Bruch, Stravinsky and Prokofiev's work in the form also get the occasional listen. Mendelssohn, a piece which I once loved, has overstayed its welcome in my ears, and I've never had much interest in the last movement which I think is a real let down after the first two. Mozart's I find tedious. Lalo's, while refreshing at first, didn't do much for me after repeated listens. I guess I'll also give a shout out to Glazunov, Saint-Saens 3, and Vivaldi's work for being enjoyable.
Still have to listen to Bartok, Britten, Glass, Dvorak, Schumann, and I'll being seeing Ades live in a few months, so I'm pretty excited for that. Am I missing any others?
