A crude joke by the Korean-British pianist Hyung-ki Joo set the tone for the evening: “I know I’m not Yuja Wang, but some girlfriends do call me Huge-a Wang.”

Mr. Joo and his comedy partner, the Russian-German violinist Aleksey Igudesman, were performing with Ms. Wang, the superstar pianist, on Monday as part of her Perspectives series at Carnegie Hall. Igudesman & Joo, as they call their duo, are trained (and skilled) musicians who imbue classical music with laugh-out-loud humor.

But their concert with Ms. Wang was riddled with jokes about her sexual appeal and Chinese heritage that ranged from unpleasant (“God, she’s so hot”) to offensive. (“It smells of sweet and sour chicken,” Mr. Igudesman said of a box with Ms. Wang inside.)

In my review, I described some of the jokes and said they were a shame, especially considering that much of the evening was delightful: Ms. Wang was as impressive as ever, and Igudesman & Joo’s music-based comedy was virtuosic.
