So much about the band SHEL comes down to family. The group's name is an acronym for the four members — Sarah, Hannah, Eva and Liza Holbrook — who happen to be sisters. They grew up in Fort Collins, Colo. and were home-schooled by their mother, but it was their dad who really pushed his daughters to learn music and singing together.
SHEL released its second album, Just Crazy Enough, earlier this month. Eva and Sarah Holbrook joined NPR's Rachel Martin to talk about how their upbringing shapes their music, and why recording an Americana cover of a Metallica song felt like the most natural thing in the world.
