He was impressed with Gaga and Bennett's vocals, stating that the concert was "charmingly effective in showing off the talents of both artists on a stage simply decorated with crystal-studded curtains".

[21] Ashley Lee of The Hollywood Reporter defined the concert as "an effortlessly powerful Bennett and a respectfully restrained Gaga pair for a decadent set of standards".

[22] A review in The Vancouver Sun stated that the "duo lights up the Queen Elizabeth Theatre" and also praised Gaga's performance onstage as a "born entertainer".

He praised the whole concert and the duo's vocal ability, saying that "[Gaga] was born to perform the American Songbook" and "[Bennett] is a national treasure whose career spans over six decades and he's still got it".

[26] Conversely, Barry Brecheisen from Orange County Register gave a more negative feedback of the show, saying that Gaga's singing ability was restrained and her untimely departures from the stage for costume changes were distracting.

"That's all the more frustrating considering her solo spotlights were the evening's standouts, outshining the almost de rigueur standing ovations Bennett garnered", the reviewer added.
