Sylvan Esso is a unique collaboration between Ameila Meath of folk group Mountain Man and Nick Sanborn, the bassist in Megafaun. Sanborn uses synths and other electronics to create pulsating grooves and swirling electronic atmospherics for Heath’s gorgeous and coquettish voice – and thanks in part to their unique sound the duo have been essentially won over the blogosphere and print publications. 

The duo was recently on the Tonight Show with Jimmy Fallon and performed “Coffee” with Questlove, which adds an extra layer of nuance to the track. 

Interestingly, her voice reminds me a little bit of Kalma Traver of Rubblebucket.
