While correcting the San Francisco Call, 26 October 1918, I ran across this article:
ANNOUNCE SECOND TRIO CONCERT
Provided the embargo on concert gatherings is raised before the date set for their second concert of the season, the Shavitch-Saslavsky-Bem Chamber Music Trio will give their next programme at the Italian Room of the St. Francis Hotel on Tuesday night, Nov. 12. Musical San Francisco is waiting for this event, for the players of the trio created nothing short of a sensation at their initial appearance last month. From all sides, musicians and critics, the opinion has been expressed that San Francisco is rich in the possession of three such superb players banded together in an ensemble organization, and that their subsequent concerts would be notable events.
Their next program exploits wonderful selections. First will come a trio, op. 56 by Charles Wakefield Cadman, a work that has been played before but has never been subjected to a revision by the author, in conjunction with Shaviteh, that marks it as a practically new composition. The Dvorak, op. 65, trio will also be given by the artists and a sonata for cello and piano by Cesar Franck will be played by Shavitch and Bem.
I was wondering who Charles W. Cadman was and found this in the Wikipedia.
