"He has naturally a superior voice, far better than many of the principal tenors who have been engaged for star opera troupes. He has, besides, much musical taste."
"The Boston Journal" said,—
"The tenor of this troupe (Mr. Bowers) possesses a voice of wonderful power and beauty."
Another paper said,—
"As most of our citizens have heard the 'colored Mario,' it is unnecessary for us to speak of his singing, as it is generally admitted that his tenor is second to none of our celebrated opera-singers."
Another said,—
"The concert given by the Sedgwick Company was a great success.... 'Mario's' fine tenor voice was never more feelingly exercised, nor more rapturously encored."
Again he is thus highly praised:—
"The 'colored Mario's' voice is unequalled by any of the great operatic performers."
