The Glow from Sylvan Esso, with backing vocals by Molly Sarlé and Alexandra Sauser-Monnig.

Together with Sylvan Esso’s Amelia Meath, Sarlé and Sauser-Monnig are Mountain Man.

Sarlé has a solo career (and a smashing Tiny Desk to go with it).

As does Sauser-Monnig, as Daughter of Swords. She has a Tiny Desk too.

No matter the permutation or combination, there is music to be reckoned with there.
