During the Soviet years, Tatarstan was part of the RFSFR (the giant Russian portion of the USSR). Now, it remains part of the Russian Federation. Their capital is the city of Kazan, which featured a conservatory.
http://en.wikipedia.org/wiki/TatarstanTatarstan borders some other interesting ethnic regions that exist under the Russian federal umbrella, including the lands of Mari El, Chuvashiya, and Bashkortostan (Bashkiriya), all of which boasted interesting composers as well. For example, the wonderful Andrei Eshpai was an ethnic Mari composer.
Thanks so much for these links, Latvian.
You're welcome! I suppose under the structure of this forum I should have included these files under "Russian and former Soviet." Since it's such a distinct ethnic group, though, I thought it would get lost in the Russian/Soviet folder, and with the possible exception of Albert Leman, these are not really Russian composers.
