Feist and Mastodon’s split single, appropriately called Feistodon, was recorded exclusively for Record Store Day (tomorrow!), but you can stream both tracks below. Feist tackles Mastodon’s “Black Tongue” from the group’s critically lauded 2011 album, The Hunter. Mastodon decided to cover “A Commotion,” a highlight from Feist’s excellent Metals album. Both artists’ disparate styles made this split single one of the most talked about Record Store Day releases of the year, and now that we’ve heard it, we can say with some confidence that it’s also one of the best.
