Touring behind their album iii, Andrew Wyatt and Pontus Winnberg shared a few moments with Chicago Chapter at Lollapalooza 2016. Winnberg described how Wyatt met their third member, Christian Karlsson, at a New York session, came to Sweden, and there was a connection. Their process of writing songs generates about two dozen per album, from which they choose about 10. "It's hard to say when you feel a song's done," said Wyatt. "I think that's something you learn over the years," responded Winnberg.
