The first release from the trio of Nels Cline, Gerald Cleaver, and Larry Ochs in a 2016 concert at Gallery5 Arts, in Richmond, Virginia, captured as part of the trio's series touring around the Northeast each December since 2015, playing what Larry Ochs describes as music that "seeks sonically to soothe, to inspire, and to conspire", in three urgent and powerful improvisations.

An extremely unique sax and drums album, as Rova leader Larry Ochs and New York drummer Gerald Cleaver take their tenor and sopranino saxophones, and drums and percussion, into the absolute darkness and stillness of the Portel Cave in the South of France, using the resonance and inspiration of the cave to record these seven incredible improvisations.
