The Le Boeuf Brothers' most recent project, "imaginist", is a collaboration with JACK Quartet, one of New York’s premier string quartets devoted to contemporary classical music. The album features a collection of longtime collaborators including tenor saxophonist Ben Wendel, bassists Ben Street and Martin Nevin, and drummers Justin Brown and Peter Kronreif.

Imaginist is structured to unfold like a book – complete with a prologue and epilogue. The term "imaginist" refers to the early 20th century Russian poetry movement characterized by sequences of arresting images and long chains of metaphors.
