The Black Swan,--This noted songstress, whose extraordinary musical talent has created so much interest and enthusiasm among distinguished musical critics, and appreciating audiences, in various cities, will give one of her attractive entertainments at Horticultural Hall, this evening. The rare talent, and the novelty of her performances can hardly fail to draw a large and fashionable audience. In addition to her own efforts to please, she will be assisted by Prof. G. Becht and his pupil. We might fill our paper with complimentary notices of her entertainments, coming from the very highest sources. In Providence, on Monday evening, her concert was very fully attended by a fashionable audience, and she was welcomed with much enthusiasm, being loudly encored at the end of every piece, and repeatedly called out. The citizens of Providence were highly delighted with her musical powers, and are desirous of a repetition of the concert. This is the only opportunity our citizens will have of listening to Miss Greenfield. The Daily Spy,--Worcester, Feb. 19th, 1852. The Black Swan gave her long expected concert at Horticultural Hall last evening, before a large and fashionable audience; and if we can judge of her success by the manifestations of applause which were made by the audience, and the opinions of the best judges, there can be no doubt that the high expectations that had been raised by the prestige of her capacities, were more than realized. Every piece was vehemently encored, and as the Assemblage broke up, every face seemed to beam with satisfaction and delight, as if its owner would say--"I feel it is good to be here." Springfield Daily Post,--Feb. 20th, 1852. The skin of the Ethiopian may be changed, and the leopard's spots also, but it can't be "rubbed out," that the Black Swan is a trump. She took all the tricks last night, winning the game completely. The public, before hearing her, had a very indefinite idea of what she was; but after her first song, there was no longer any doubt. It was amusing to behold the utter surprise and intense pleasure which was depicted upon the faces of her listeners; they seemed to express, "Why, we see the face of a black woman, but we hear the voice of an angel: what does it mean?" It certainly is astonishing, and we were astonished with the rest. Her voice is of extraordinary compass, the tone clear, rich and full; and the execution very tasteful. Even with the memory of Jenny Lind, Kate Hayes, and Parodi, fresh within us, we cannot but record our opinion that Miss Greenfield is a singer of extraordinary merit, who will yet win a fame scarcely second to any cantatrice who has appeared before the world, and with every step she takes in public, we shall look to see fresh laurels upon her ebon brow. The Plain Dealer, Sat. Feb. 28th, 1852.
