Mary-Kate Olsen spent Thursday night at the Kills’ Alison Mosshart and Jamie Hince concert.

It was a pretty happening night–a fire was detected on the roof and firefighters showed up!

It turns out it wasn’t too big a deal, and the concert played on. A firefigter even took the time to yell “Rock and Roll!” into the mike, according to Style.com.

“They’re so good together,” Mary-Kate said of the concert. “It’s like they’re in their own little worlds and totally in their element onstage.”

MK also mentioned that Alison’s dancing onstage was very much like her own at home!

Other celeb attendees included Agyness Denn, Alexandra and Theodora Richards, Kate Moss and Lily Cole.
