The title track to The Oh Hellos' 2015 album Dear Wormwood beautifully captures the spirit of an album that's all about identity. Brother-and-sister duo Tyler and Maggie Heath shaped the record's concept around the idea of a character who writes letters to a tormentor, inspired by C.S. Lewis' The Screwtape Letters.

The song "Dear Wormwood" has a simple yet haunting chorus — "I know who you are now" — that marks an eerie turning of the tables and transforms it into an epic composition about defiance. "Dear Wormwood" translates superbly to a live environment, with the entire nine-person ensemble expressing its restrained energy.
