Wye Oak’s Jenn Wasner records synthy, reberby music on her own under the name Flock Of Dimes. And as Flock Of Dimes, she’s lately been on tour with solid-gold dance-poppers Sylvan Esso. Together, Wasner and Sylvan Esso recently took part in the A.V. Club’s A.V. Undercover video series. Wasner did a pretty stunning version of Crowded House’s searching 1986 nugget “Don’t Dream It’s Over,” and she got help from both members of Sylvan Esso. Meanwhile, Sylvan Esso did their own entry in the series earlier this week, and I don’t know why we didn’t post it; it must’ve been a busy day. They covered Gillian Welch’s coldly lovely 2001 Americana song “Everything Is Free,” and Wasner harmonized with Sylvan Esso’s Amelia Meath for the entire length of the song. Both covers are straight-up collaborations, and Flock Of Dimes and Sylvan Esso will release both of them as a split single later this year. Watch both performances below.

That split single is out 11/27 on Partisan.
