The noise-pop duo Sleigh Bells stopped by Rolling Stone this week before a pair of sold-out shows in New York City to chat about their second album, which they've been working on while touring for their debut record Treats over the past year. "Emotionally, it's a really heavy record," guitarist and producer Derek E. Miller says of the new tunes. "Even the early demos that we have now, a lot of the stuff that Derek has recorded, sounds more immense to me," says singer Alexis Krauss. "It sounds really huge, so there's going to still be tons of volume."
