A Great Big World and Aguilera also performed the song at the 2013 American Music Awards on November 24, 2013. With her hair in a braid and wearing a muted black dress, Aguilera sang an original verse midway through the performance, which included a string section and a fairly bare stage. With A Great Big World's Chad King manning the keyboard, the group's Ian Axel sat at the grand piano and stamped his feet furiously as 'Say Something' approached its emotional climax," according to "Billboard"s Jason Lipshutz. Lindsay Dreyer of "Wetpaint" wrote that "Taking her rightful place center stage in a floor-length black dress and braided updo, the 32-year-old pop diva harmonized perfectly with the group's lead singer Ian Axel, who worked the piano with passion and poise. Xtina's rich yet breathy tone offered just the right amount of strength and vulnerability — a side of Christina we haven't seen in a really long time." Dreyer finished the review stating, "If tonight's AMA performance is any indication, Christina is on the brink of a major music comeback — and we can't wait!." The band also performed the song at the 2013 Victoria's Secret Fashion Show on December 10, 2013. However, Aguilera did not perform the song with them as a duet, due to scheduling conflicts of "The Voice". Aguilera also performed the song in Malaysia in a private concert without the band on March 28. The duo and Aguilera also performed the song during the New Orleans Jazz Festival. She gave a one-and-a-half-hour-long show and then invited the band to perform the song in front of a large crowd on May 2, 2014. The band (sans Aguilera) sang the song on the September 6 episode of "Last Week Tonight" in a duet with comedian John Oliver to mourn the loss of the Russian space geckos.
