The Mastodon Record Store Day split release with Feist, lovingly dubbed 'Feistodon,' is no longer relegated to a super rare and limited item that was issued on one day. The metal behemoths and the female indie rocker released a split, in which this odd pairing covered one another's songs. Only 5,000 copies were pressed and they sold out in a hot minute, understandably so. But we've got good news for fans of both acts. Digital versions of the singles are now available here. But wait, there's more!
