Opera News magazine – March – review by Henson Keys of Marcelo's “20 Years on the Opera Stage.”

“There is much to admire and enjoy in this new disc by Argentine tenor Marcelo Alvarez. . .Alvarez sings beautifully, with pure tone, ravishing pianissimos and a romantic ardor that perfectly suits these arias. The entire disc is infused with elegance and nobility of phrasing, as well as an intelligence that makes the approach to each aria subtly but distinctly different. . .exquisite beauty and much emotion in the tone. . .golden tone and haunting lyricism. . .Alvarez gives us much glorious vocalism and a maturity of interpretation that has deepened with time and experience.”
