Thus spoke "The New-York Evening Post:"—
"The Hyers sisters are colored, and, to the musical instincts of their race, have added careful musical training. Miss Anna Hyers possesses a flexible voice of great compass, clear and steady in the higher notes. Miss Emma, the contralto, has a voice of great power and depth; qualities which, in impassioned strains, give it a richness not often heard in chamber concerts.
"The gem of the evening was the 'Miserere' scene from 'Il Trovatore,' which was skilfully rendered by the sisters, Miss Emma singing the tenor part with very fine effect.
"A duet by Millard, sung by Miss Anna and Mr. J. Luca, was also remarkably well rendered; Miss Anna displaying the admirable qualities of her voice and her careful training to the greatest advantage.
"The audience was enthusiastic, and the encores were frequent."
Said "The New-York Tribune,"—
"A concert was given last evening by the Hyers sisters at Steinway Hall. These are two young colored girls who have received a musical training in California, and who are by no means mere 'Jubilee' singers, as the programme of last evening clearly shows. It embraced several airs and duets from 'Martha' and 'Trovatore;' the last being the 'Miserere,' which called forth hearty applause."
"The Evening Telegram" alluded to them in the following complimentary terms:—
... "The selections last evening embraced a high order of music, operatic and otherwise; and were rendered with a taste and grace that elicited frequent applause.
"One of the young girls possesses a very pure soprano, the other an equally excellent contralto voice; and, singly or together, their execution is marked by a refinement, culture, and attractiveness that deserve first-class audiences and first-class appreciation."
