Stevie Wonder played a free pop-up show at the Armory Mall in Washington, D.C., on Monday. The show was part of a news conference announcing the extension of Wonder's "Songs in the Key of Life Performance" tour.

The concert in Washington was followed by a concert at Dilworth Park in Philadelphia later that afternoon, where Wonder treated fans to hits including "Superstition" and "Uptight." The R&B legend also took questions from the media and spoke against gun violence. From there, the singer then headed to New York City's Central Park for his final gig in the evening, according to The Washington Post.

Wonder has been touring on and off since November of last year, when he performed his first "Songs in the Key of Life" show at Madison Square Garden in New York City. The final 20 shows are being promoted as his last time performing the 1976 album, which includes hits like "Sir Duke," "I Wish" and "Isn't She Lovely," according to The Wall Street Journal.
