Current Slipknot drummer Eloy Casagrande was challenged by Drumeo to learn Mastodon's "Blood And Thunder" as fast as he possibly can, and there was definitely some cursing involved.
Still, Casagrande tackled the song in roughly 42 minutes and even got the approval of Mastodon drummer Brann Dailor, who said: "I'm very, very very stoked to hear someone at Eloy's caliber of playing to do 'Blood And Thunder'. That's such a cool thing, yeah. Oh my God amazing Eloy you did an amazing job. I love you. You're the best. That was incredible."
