Wye Oak are an indie folk rock duo from Baltimore, Maryland, USA, composed of Andy Stack (drums, keyboards, backup vocals) and Jenn Wasner (vocals, guitars). Their sound has been described as "earnest folk-influenced indie rock with touches of noise and dream pop". Wasner sings lead vocals and plays electric or acoustic guitar, while Stack plays both drums and keyboards, playing the drums with his feet and right hand, and the bass line with his left hand.
The band were formed as Monarch in mid-2006, before changing their name to Wye Oak, a reference to the former state tree of their home state of Maryland. They released their first album If Children independently in 2007 and subsequently signed to Merge Records in 2008. The label re-released If Children that year, and a second album, The Knot, followed in 2009
