Thanks to his cascading delivery, pioneering jazz pianist Earl Hines transformed showtunes and standards: His brief live recording of “Ol' Man River” lets loose a signature flurry of lively melodies, while his 1972 take on “Sweet Georgia Brown” showcases an especially animated exchange with fellow pianist Jaki Byard. And a duet version of “Caravan” with drummer Cozy Cole becomes an excitable 10-minute celebration.
