question: What is the name of the person that Robert Christgau stated it was a relief to hear him eassay the show tunes?
context: Overall, reception of the album was positive. Stephen Holden of Blender called Wainwright's tribute "a fabulous stunt in which a gay singer channeled the spirit of the ultimate gay icon", and declared the album was "as good an introduction to the great American songbook as any". Pitchfork Media's Stephen Troussé wrote that Wainwright "elegantly outdoes [Garland] on a couple of the ballads" and also compliments guest performer Martha Wainwright, "who turns in a stunning, showstopping 'Stormy Weather' in an appropriately brazen bid to steal the show". In his review for Rolling Stone, Robert Christgau stated it was "a relief to hear him essay the show tunes and Tin Pan Alley chestnuts of this tribute album". Furthermore, he wrote that the songs "expand [Wainwright's] melodic compass", allowing him to "bring something new to them too – namely, sexuality in the sensuality as opposed to gender-preference sense". Dave Hughes of Slant Magazine had positive comments about the album: "That Wainwright has the temerity to cover such a bona fide classic—and the chops to pull it off without breaking a limb or his brain—speaks both to his ambition and to his prodigious abilities."The album did receive some criticism. After noting Garland's lifelong attempt to master pitch and articulation, Christgau claimed Wainwright's habit of "slid[ing] past notes and draw[ing] out the final syllables of lines are signatures indistinguishable from tics". Entertainment Weekly's Chris Willman wrote that Wainwright's "delicate upper range is nicely attuned to some of the ballads, but anything that requires belting is pretty much a loss". Mark Edwards of The Times called Wainwright's performance an acquired taste, stating his "trademark delivery" is "lazy and somewhat slurred". Dave Hughes' review pointed out Wainwright's "problem with the brassy high notes in an otherwise energetic take on 'That's Entertainment'", but admits it would be unfair to hold this against him since Garland's live performance was not perfect either. Hughes appropriately notes, "Ain't nobody perfect".
