Chicago EDM group Krewella was feeling quite honored before their headlining set on the second day (Aug. 2) of Lollapalooza in the Windy City’s Grant Park.

“This is probably one of those full-circle nights for us, because I remember coming to this festival as a kid,” Krewella’s Yasmine Yousaf told Billboard backstage at the festival, which you can watch below. “Coming to our hometown and playing a legendary festival like Lolla couldn’t be any better."

Sisters Yasmine and Jahan Yousaf also discussed their pre-show rituals, which include scanning the audience during an opening set to see what music the crowd is responding to.

“In some territories trap doesn’t go off as much, so we’ll know ahead of time not to play as much trap, so we’ll kind of feel out the crowd at first,” Jahan explains. ““We always try to catch the tail end of someone else’s set.”

Krewella, which teased some new material at this year’s Electric Daisy Carnival, is about 50 percent done with their sophomore album, the sisters say.

“We keep writing songs, and songs we loved two months ago now will never make the album,” Yasmine says. “We’re taking maybe 50 percent of the next four months off to really crank the second album out and focus on it, and try to finish birthing it.”
