This is actually more of a "name that performing group" - Steinberg (1883-1946) wrote two quartets, Op.5 (1907) & Op. 16 (1925) - neither is available on this side of the former Warsaw Pact line - can any of our Russian friends tell me if they were ever recorded/released in Russia?
Apparently, he mostly resided in St. Petersburg for the vast majority of his life (whether or not he stuck it out during the Nazi-Germany invasion attempt, I don't know - I don't have detailed biographical info on him - not even a complete works list.) The first quartet is published in the West, but not the 2nd, from what I've been able to see.
Any help would be greatly appreciated.
