First, I also like Steinberg's Symphony No. 4 very much, highly enjoyable music. It's a work full of elan, vigour and memorable tunes, pure delight. I knew it as a broadcast recording for quite some years and was therefore very happy about this (still rather new) Dutton disc.
Now, as for the problems with the broadcast recording Maris speaks of, here is the story: this symphony was broadcasted by the BBC in the mid-1990s. A friend of mine (his name is Terry – some of the members here know him) listened to it and already found the first few minutes so exciting that he decided to record the symphony. However, as a consequence, in his recording – which is the one circulating online in various sources – the very beginning of the symphony is missing. Basically it's the slow introduction of the first movement which he didn't record. Anyway, this symphony lead him into collecting Soviet symphonies, and he now has one of the largest collections of Melodiya LPs I am aware of.
Holger, yes I used to correspond with Terry (think he was a professor of Music somewhere in the UK) and he had a huge collection of not only Melodiya LPs but radio broadcasts of Russian and Soviet composers that I've yet to see any commercial recordings available. He had sent me a listing of recent acquisitions back in 2000 that had me spinning in my chair. They were all radio broadcasts...I never heard from him after about 2005... I'll see if I can reach out to him.
I emailed Terry and the message came back "invalid email address"
