The video for ‘A Commotion’ lets the user crossfade between the Feist and Mastodon versions of the song.

Unlikely collaborators Feist and Mastodon teamed up to cover each other’s songs on a split for Record Store Day. Feist covered ‘Black Tongue,’ and Mastodon put the metal in the Metals song. The video for the latter features Feist as the world ends, but this new interactive version lets the listener mashup the versions with a crossfader. A digital version of the 7″ is available now.
