The new material from what is likely sessions from their third album have been making their way out, and the latest comes from the soundtrack to “Sex Tape.” Introducing “Undone.”

Inara George and Greg Kurstin have put together a song that’s among their most uptempo and modern sounding. The harmonies are a bit different from their previous material, but it sounds incredibly fresh and ranks among their most catchy. Clocking in at a mere 3:13, it’s a quick romp, and highly enjoyable. It’s great to see their resurgence, which makes the wait until 2015 for the third album even more difficult. But if songs keep sneaking out, I can deal.
