The firestorm of a song saw the Brooklyn-based duo experiencing two moods simultaneously. “So something like “Tell ‘Em” is preach-y without being righteous,” Derek Miller, one half of Sleigh Bells, said. “It’s like we’re disappointed but optimistic. I love that in vocalists.” Miller decided to go for a heavier sound on this particular song. “It has this intense melody on it. I was afraid to do it for so long because I had abandoned heavy drone for a few years. But it was just there, always in the background and I was just craving it.”
