Writing for Turner Classic Movies, biographer Jonathan Riggs observed that Garland had a tendency to imbue her vocals with a paradoxical combination of "fragility and resilience" that eventually became a signature trademark of hers. Louis Bayard of "The Washington Post" described Garland's voice as "throbbing", believing it to be capable of "connectwith [audiences in a way no other voice does". Bayard also believes that listeners "find it hard to disentwine the sorrow in her voice from the sorrow that dogged her life", while Dowlin argued that, "Listening to Judy sing ... makes me forget all of the angst and suffering she must have endured." "The New York Times" obituarist in 1969 observed that Garland, whether intentionally or not, "brought with her ... all the well-publicized phantoms of her emotional breakdown, her career collapses and comebacks" on stage during later performances. The same writer said that Garland's voice changed and lost some of its quality as she aged, although she retained much of her personality. Contributing to the "Irish Independent", Julia Molony observed Garland's voice, although "still rich with emotion", had finally begun to "creak with the weight of years of disappointment and hard-living" by the time she performed at Carnegie Hall in 1961. Similarly, the live record's entry in the Library of Congress wrote that "while her voice was still strong, it had also gained a bit of heft and a bit of wear"; author Cary O'Dell believes Garland's rasp and "occasional quiver" only "upped the emotional quotient of many of her numbers", particularly on her signature songs "Over the Rainbow" and "The Man That Got Away". Garland stated that she always felt most safe and at home while performing onstage, regardless of the condition of her voice. Her musical talent has been commended by her peers; opera singer Maria Callas once said that Garland possessed "the most superb voice she had ever heard", while singer and actor Bing Crosby said that "no other singer could be compared to her" when Garland was rested.
