ZHARRA — London

Jazz is the organizing principle. Zharra keeps a handwritten notebook — black, unbranded — where she logs every live set she attends, noting the venue, the players, what shifted between the first and second half. Ronnie Scott's staff greet her by name. She once described two performances by the same pianist, months apart, with enough specificity to settle an argument at the table. Twenty-nine, Brazilian, based near Victoria.
