Mighty Vertebrate is the International Anthem debut from Anna Butterss. The Adelaide born bassist / composer has been a first call for LA tour and studio work since relocating there in 2014 - racking up credits with notables across the experimental, jazz, and pop worlds alike - but their most notable contributions to the burgeoning LA scene have been as a 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."
