Blood Ceremony is easily the heaviest flute band ever. I don’t care what stupid award the Grammys can find to present Jethro Tull(sham!), Alia O’Brien and co. can seriously bring it. Not only an accomplished flautist but her hallowed organ work is littered through their albums, adding a great 70s touch to the heavy doom riffs that already dominate the Blood Ceremony sound. Equal parts intimidating and exciting, Blood Ceremony has found a new way to refresh the heavy genre, while completely unafraid to wear their very obvious influences on their sleeves. Good on ’em.
