What exactly are Mastodon up to?

The following images have surfaced on Mastodon’s Twitter and guitarist/vocalist Brent Hinds’ Instagram accounts. The tweet was posted with the hashtag #TheMotherload which hints at a music video for the track of the same name from their latest release Once More ‘Round The Sun. I guess we’ll have to wait and see if more clues surface on social media or if the video just drops like a blessing from the sludge rock gods.
