Earlier this year, Disclosure reunited with an old friend. As the English dance music duo neared the finish line on their second LP, Caracal (due out September 25th), they invited singer Sam Smith to come hang out at their new studio in London’s St. John’s Wood neighborhood. “It was really exciting, ’cause we hadn’t seen him in so long,” says Howard Lawrence, sitting next to his older brother and bandmate Guy Lawrence. “We had three whole days to hang out with Sam and write, which are two of my favorite things to do.”
