In the 1960's VEB Deutsche Schallplatten, the East German Record company released an LP of Franz Konwitschny conducting the Bruckner Symphony No. 4. It was released on their Eterna label (8 25 504). As was often the case, this recording was licensed to other companies for distribution outside of the Eastern Bloc. On the Eterna LP, the orchestra is the Vienna Symphony Orchestra, but on many of the western pressings (most notably Eurodisc on several of their re-packagings) the orchestra was listed as the Leipzig Gewandhaus Orchestra. So which orchestra is it? It's Vienna. Eurodisc made an assumption but Eterna was there when the recording was made.
