For Fans of John Coltrane

Damien Chazelle's film is not really about jazz. The music is almost a MacGuffin. What it captures with uncomfortable precision is the psychological cost of the demand Coltrane placed on himself: the hours, the bleeding, the refusal to accept that good is ever good enough. Fletcher is a monster, but the compulsion he exploits is one Coltrane would have recognised. Watch it, then put on Giant Steps and hear how many impossible things he chose to do in three minutes.

The four movements -- Acknowledgement, Resolution, Pursuance, Psalm -- are not track titles, they are the architecture of a devotional act. Coltrane wrote the liner-note poem himself. The suite has more in common with Bach's B Minor Mass or Arvo Part's Spiegel im Spiegel than with any bebop record. If you approach it as background music you will miss the point entirely. It rewards the full forty-five minutes of attention, ideally alone, ideally in the dark.

Described by its makers as 'rhythm violence,' Thumper has no melody, no harmony, no comfortable groove. It has pulse, momentum, and the feeling that any relaxation of focus will destroy you. That describes Coltrane's late period as well as anything. The game does not ask you to enjoy yourself in any conventional sense. It asks you to endure, to adapt, and to be changed by the process.

Ralph Ellison finished his novel in 1952, five years before Coltrane joined Miles Davis's first great quintet. Yet the novel's framing device -- an invisible Black man in a basement lined with 1,369 light bulbs, listening to Louis Armstrong -- prefigures everything Coltrane would do: the insistence on being heard by a society that would prefer not to hear, the use of music as the one space where the full complexity of a person cannot be edited out.
