Many vinyl records are invaluable documents of their time, and hardly any series shows this as clearly as the Cologne recordings in the Electrola Collection. The re-release of these classics and rarities has met with an enthusiastic reception from  music-lovers and critics alike, and after the change from EMI Classics to Warner Classics the series is being continued under the name 'Cologne Collection'. The new additions cover opera and operetta, choral music and Lieder as well as the very first concerto recording made by top clarinettist Sabine Meyer.

Franz Schubert suffered failure after failure with his attempts to write for the stage, and this also applied to his incidental music to Hermina von Chézy's Rosamunde. It is impossible to say today why the play was a flop – the original text has been lost in the meantime.

However, Schubert's highly romantic overture and the orchestral intermezzi survived as concert pieces, and Robert Heger's complete recording of 1966 showed that the music can stand alone. As one of the leading Lieder singers of her day, Anneliese Rothenberger was predestined to perform the vocal part in the Romanze.
