TLC perform 'Waterfalls' live in Houston, TX NRG Stadium July 30, 2017

About 3/4 of the way through their set headlining the I Love the 90s: the party continues Tour, Chili and Tboz said they weren't completely feeling the love from the audience in the front, at which point Tboz said, "Maybe the people in the back need to come up front. This is a TLC party! Come on people in the back!" All the fans in the arena were allowed to make their way to the front in order to be close to the girls as they performed "Way Back", "No Scrubs", and "JoyRide", "Waterfalls" and a few more songs.
There are a few moments in this video where my finger got in the way of the camera on my phone though lol.
