"Nat Baldwin's AUTONOMIA III: Endnotes extends his series of experimental works for solo double bass, marking his third and final release of 2020. Its precursors include AUTONOMIA I: Body Without Organs (Shinkoyo) and AUTONOMIA II: Recombinations (Traced Objects). Endnotes embraces perhaps an even more extreme form of reductionism than the previous works. Like its predecessors, however, even when engaging the highly concentrated approaches associated with noise and new music, the expressivity and energy generated through the spirit of free improvisation remains a powerful presence.

The album opens with "polarities", featuring the bass lying flat on its back, a strategy that provided the closing tracks on the previous two albums. The metal peg at the bottom of the bass, used to adjust its height, acts as the primary sonic source by removing it to attack the two wires and its surroundings below the body, as well as the strings below the bridge, creating a polyphony of overlapping textures.

Bringing the bass back to its upright stance, the next track, "hydra", emphasizes repetition and velocity through aggressive circular bowing techniques aided by an additional bow jammed between the strings and fingerboard. The position of the prepared bow stays the same for the title track "endnotes", but the right hand shifts to microscopic spiccato bursts and hushed percussive gestures.

The album closes with "currents", celebrating the high harmonic range of the double bass with a patient arch of expanding dynamics and density, its peak providing the proper climax to an explosive body of work produced by Baldwin over the past year."-TripTicksTapes
