Harmony is the follow-up to Never Shout Never's critically heralded debut What Is Love?, which bowed at #24 on the Billboard Top 200 album chart, #2 on both the Alternative and Rock charts, and #11 on the Internet album chart. The album was produced by veteran producer Butch Vig, who is best-known for his work with Green Day, Nirvana, and Smashing Pumpkins.
