前ｽﾚに載せたソンドラ・ビアンカについてです。パーフェクト情報ではないですが。
さらに邦訳でなくてｽﾏｿ。ちなみに文中に出てくる「her father」というのは
Lazare氏のことです。

Sondra Bianca was once a well-known American concert pianist who worked for
her father's recording business. Apart from standard repertoire she recorded a
couple of works altogether new to the catalogues, such as the Massenet piano
concerto or the lst piano concerto by John Field. Gerhard Arnoldi, now working
for NDR Hamburg, confirmed the identity of this recording and gave the author
some interesting information on what the Lazare business was about in general.
Some of Lazare's productions were released under fake names a little later on
Rondo and Rondo-lette, two of Oberstein's labels from the late Fifties and early
Sixties.
