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.”

“I had just gotten off of a bunch of touring at the end of 2022 and just wanted to write music,” says Butterss. “The best way for me to do that, I’ve found, is to set myself a discreet and focused task."

I’m going to make a song where the bass doesn’t function in the role of a bass.
I’m going to work on this for an hour and then I’m going to stop.
I’m going to make a song that uses groups of three-bar phrasing.
I want to sample something and make it into a song.
I’m going to start with a drum machine.

The music itself reflects that structure beautifully, with the material being tightly
composed and melodically realized by Butterss well in advance of production concerns. Here they reconvene a group of trusted longtime collaborators to bring their compositions to fruition: Ben Lumsdaine (drums, guitar, production), Josh Johnson (sax), and Gregory Uhlmann (guitar), plus a smoking guest appearance from Jeff Parker. The breadth and scope of the results might have been difficult to achieve otherwise. From the Robbie-Shakespeare-in-groove-mode intro to the album opener “Bishop” to the spacious cinematic doom of “Seeing You”, there is a lot to wrangle into one cohesive concept. On Mighty Vertebrate, Butterss and crew do just that.
