We had a blast at the Earl last night! A great pre-tour warm up before we break out the lasers and LED screens. Our good pal, John Baizley from @yourbaronessjoined us, we had so much fun, we’ve invited him join us on stage during The Poisonous Weapons Tour to play a special set of Mastodon songs we haven’t played in a long time! We’re really excited to bring this special set on the tour. It’s going to epic! Who’s ready to party?
