http://m.youtube.com/watch?v=IDMls88rRX0 The above link is to a YouTube post of Gunter Kochan: Symphony No. 4, Part 1. The sound quality surprised me as I did not expect much from a compressed stream. The cellos are a bit muddled, but there ain't no etch in those strings.
It's from a rare German vinyl release on NOVA.
Let me know what you think. Maybe my ears are failing me.
