I remember the Steinberg 4th broadcast because I listened to it and taped it! It must have been in 1994 because at the time I was writing a dissertation on Russian music of that period. It was just before I went to Russia and spent several weeks in archives and libraries. It was part of a series which included A. Krein no.1 (Adrian (?) Leaper cond.), Popov Chamber Symphony and Lyatoshynsky no.1 As a result of this, the Krein was subsequently recorded by Brabbins and the Philarmonia and released by Largo, while Lyatoshynsky is well recorded.
Dear Bobyor
We surely need more from Krein's family their role is underrated
