Antonio, nether Glazunov nor Myaskovsky were composers about whom I ever cared a lot, perhaps mistakably. Also, and maybe regrettably, not a lot of Interesting” performers play Glazunov’s and Myaskovsky’s works.
Myaskovsky has violin and cello concertos and 4040673 symphonies and a dozen quartets. “Olympia” label year after yeas issues the Myaskovsky’s CDs and it probably would be a good place to start. There is a wonderful Russian site:
that is quite good in English and that might be a good guide for you. If I were you I would start from Myaskovsky’s Symphony #VI and his Cello Concerto. Be prepared for a slightly weepy and overly pretentious, "too much Russian" music.
Glazunov’s some quarters are “near OK” and some of his symphonies are survivable (for instance the Symphony #4 and #5). Neeme Järvi played a lot of Glazunov and I would certainly hunt for Järvi performances.
Still, to me, Myaskovsky and Glazunov are Rimsky-Korsakovs with talent deficiency. They remind me the music of the infinitely wiling to say something Nikolay Medtner that itself might be OK from certain perspective but… But after you listen any of Medtner 25554 piano concertos (his “skaskas” are better) along with one single phrase of Rachmaninoff then you instantaneously begin to feel why Myaskovsky, Medtner and Glazunov were (in a way) Russian’s “B” composers.
Surely, I do not mean to sound demeaning but… hey… you will be the judge.
