"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." So great was the success of the talented troupe in the metropolis, that when they visited Brooklyn they were already fully advertised, and a general and very eager desire was manifested in that city to witness their performances. So great was this desire, that, said "The Brooklyn Daily Union," "Not only was every inch of standing-room in the Young Men's Christian Association Hall occupied, but the ante-room and even the stairway were completely jammed. In spite, however, of the uncomfortable crowding, every one was pleased to be present, and all were delighted with the concert. "The young ladies are gifted with remarkable voices, and sing together with perfect harmony; displaying the full compass and beauty of their voices, which are clear and sweet. "Mr. Wallace King's rendering of Tennyson's beautiful song, 'Come into the garden, Maud,' was really exquisite, and was followed by a vociferous encore. The concert was one of the finest of the series." But notwithstanding the many critical tests to which these young ladies had been subjected all along from California to New York, and despite the fact that their journey had thus far been marked by a continual series of triumphs,--the thick walls of color-prejudice everywhere yielding before the force of their rare musical abilities, their almost marvellous sweetness of song,--they now approached with feelings somewhat akin to dread the "modern Athens," that acknowledged centre of musical and general aesthetic culture, Boston, whose critical audiences ever receive coldly, at first, all newcomers, and who, guided by their own judgments, and having their own standard of merit, never yield praise because it has been accorded in other sections.
