A number of orchestral 78rpm records were issued with no conductor credited on the label.
Schubert – Rosamunde – Overture
Sutherland Orchestra
Beltona 646
Matrices C6520, 6521
Recorded c1924 (issued November 1924)

The issue date given above is for the original ACO record on G15527, where it was credited to the Grosvenor Orchestra. This also was a pseudonym, covering both original recordings and reissues, including American Aeolian Light Orchestra and British Aeolian Orchestra and Regent Symphony Orchestra records.

My copy of this record is fractured, and I have done my best to ameliorate the regular click and thump which lasted through both sides of the record.

No conductor is named on the label or in the matrix listings, though George W Byng was the most frequent conductor for other sessions with this group.

Liszt arr. Sommer – Liebestraume
Drigo arr. A Goossens – Les Tresors de Columbine, Air de Ballet
Viennese Symphony Orchestra
Piccadilly No.113
Matrices XX 1160-3 (78), XX 1161-3 (68)
Recorded c1930

Records on the Piccadilly record label have appeared on this site before: pseudonymous recordings of tenor and violin solos. The latest record given here is the rather vaguely named “Viennese Symphony Orchestra”. The Liszt side obviously received rather more play than the Drigo, and is consequently more worn. I’m unsure whether the arranger of the Drigo piece is connected to the famous Goossens family.

Kronberger and Marriott – The Frog King’s Parade (March)
Mozart – Marriage of Figaro – Overture (slightly abridged)
Viennese Orchestra
Piccadilly No.338
Matrices: XX 2016, 2034
Recorded c1930

This may be the same group as the Viennese Symphony Orchestra above. The orchestra appears not to have oboes or bassoons – a prominent bassoon line in the Mozart is played by a bass clarinet. Bars 18 to 34, 236 to 243 and 266 to 283 are cut from the overture.

Nicolai – The Merry Wives of Windsor – Overture
The New State Symphony Orchestra
Decca K.634
Matrices 30221, 30222
Recorded early 1930s – reviewed in Gramophone February 1932
