Anna Butterss / MIGHTY VERTEBRATE

‘Mighty Vertebrate’ is the International Anthem leader debut from Adelaide, Australia-born bassist and composer Anna Butterss.

Butterss has steadily become a first-call for tour and studio work since moving to Los Angeles (after a stint in Bloomington, Indiana) in 2014. They’ve racked up credits with notables across the indie, jazz, and pop worlds alike – including Makaya McCraven, Phoebe Bridgers, Jason Isbell, Andrew Bird, and Daniel Villarreal – but their most notable contributions to the burgeoning West Coast creative music scene have been as a core member of both Jeff Parker’s ETA IVtet and rising proto-trance supergroup SML, who Pitchfork says “represents the thrilling next phase of a vibrant L.A. community.”
