‘Cameron Winter at Carnegie Hall’ Review: Paul Thomas Anderson Directs a Rapturous Solo Concert Movie Built Around the Songs — and Haunting Sound — of Cameron Winter

The slow rolling piano echo through the hall like a rhapsody from the deep. The sound is rich, lustrous, bottom-heavy, grand. And that voice! Winter sings in a low baritone (and occasionally a high one) of astonishing power, the notes hanging there in a suspended quaver so bold it’s hypnotic.
