Tonight, the 2015 Grammys kicked off with AC/DC as the opening performance. With flashing lights and cheers from the crowd, host LL Cool J introduced the band who was already killing it on stage. It was definitely the right way to get the party started. The best part of their performance was seeing tons of celebrities and audience members, including Katy Perry, rocking out with devil horns on as the band played “Highway to Hell,” surrounded by flames on stage.
