Video and photo evidence from the concert shows the rapper in a suit, wig, beard and large nose - looking suspiciously akin to a Jewish stereotype, with many calling it anti-Semitic.

Since footage of the performance, which took place at the opening of a music video-centric exhibit at Seattle's EMP Museum, found its way onto the Internet, Macklemore has been criticized for his choice of costume - which, according to Seattle Times journalist Lynn Jacobson in the caption of a photo from the concert, the rapper said he found after he "went to Costume Display," adding that he felt "like a man for the first time today."
