Brightness and density are scored against this record's own sections, not against music in general — they say how its parts differ from each other, and nothing about how it compares to anything else.

Separated into parts by a source-separation model, so each lane is the instrument it names.

Every moment against every other. Squares on the diagonal are sections; a bright patch off it is the record recognising itself — the second chorus meeting the first.

Measured from the YouTube master on . Section labels describe how the energy of the recording moves, not its musical form — a machine can see loudness climb and jump, it cannot hear a chorus arrive. Anything we were not confident enough to state is left out rather than shown with a caveat.

  1. Ranked No. 1 in Blues

    One man, one guitar, and a sense of pursuit that no amount of retelling has managed to domesticate. The myth around Johnson is a distraction from how precise the playing actually is.
