In one of the more unorthodox pairings on a Record Store Day that looks to be full of them, Feist and Mastodon have collaborated on a 7" single that finds the artists covering each other -- and now you can hear the results.

Dubbed 'Feistodon,' the record kicks off with Feist covering 'Black Tongue,' which originally appeared on Mastodon's 2011 release 'The Hunter'; on the B side, Mastodon tackles 'A Commotion,' drawn from Feist's most recent release, 'Metals.'

The collaboration was sparked by a chance encounter when both artists guested on Jools Holland's U.K. talk show. As Mastodon's Troy Sanders put it, "The idea is for Mastodon to cover a Feist song and throw some hair and dirt on it. [Feist and her band are] going to take a Mastodon song and pretty it up a little bit."

But not too pretty, as Feist explained: "If people are expecting a cute twee cover of a metal song they have a big surprise comin."

Have a listen to both tracks, embedded below. Did Mastodon make Feist's song hairy and/or dirty enough? And was Feist able to wrestle a little lipstick onto Mastodon's music? You decide:
