The Vassar College Choir, over 80 singers under the direction of E. Harold Geer, made its New York début with a concert in Town Hall.   The New York Times applauded the singers’ “varied program” and their “commendable attack, unusually clear enunciation and fidelity to pitch.” Works by Palestrina, Bach and Thomas Norris and premières of songs by André Caplet and Jean Roger-Ducasse were sung in Latin, and “an interesting group” of “traditional carols from Catalonian, Polish and Russian sources” were presented in arrangements by Professor Geer.
