Baltimore’s Wye Oak (who started as Monarch) are Andy Stack and Jenn Wasner, and get described as either indie-rock-infused folk, or folk-infused indie rock. Either way I like it.
Tween collects things recorded between their albums Civilian (2011) and Shriek (2014) though it came out later. Ashley North Compton did the cover (as she did for Shriek).
