A studio encounter between pianist Sylvie Courvoisier and electric guitarist Mary Halvorson, both using sophisticated techniques giving unique voices to their playing styles, in a set of improvisations that balance playful, subtle, energetic, and emotional playing.

First recorded meeting of Chris Corsano (drums), Sylvie Courvoisier (piano), and Nate Wooley (trumpet) in the studio in Brooklyn, 2015, for a completely open, sensitive set of improvisations that are constantly on the edge, at times explosive, and always in a focused dialog.

"Battle Pieces" was conceived as a background for an improviser, using linguistics, tape processes & aleatoric concepts to fashion an ever-shifting composition that supplies the soloist with information within the context of an ever-changing series of densities, velocities and silences.
