Diana Krall's trademark contralto is cool, intimate, and graceful, its contours perfectly suited to small ensembles -- particularly the trio with which she made her name during the '90s. On her previous date, the 1999 platinum-seller When I Look in Your Eyes, a program drawn from American Songbook repertoire (both classic and obscure) that spent 62 weeks at No. 1 on the jazz charts, Krall extended her scope, augmenting the trio and quartet format with a Johnny Mandel-arranged orchestra. With The Look of Love, her Brazilian-flavored follow-up, Krall and producer Tommy LiPuma pull out all the stops, roping in the arranger Claus Ogerman and two (count 'em, two) symphony orchestras, as well as guitar guests Dori Caymmi, John Pisano, and Romero Lubambo and percussion masters Paulinho da Costa and Luis Conte.Chief supporting musicians include such jazz greats as guitarist Russell Malone, bassist Christian McBride, and drummer Peter Erskine.The sound is lush and restrained; the production values are decidedly pop, right down to the Bruce Weber photographs on the inner sleeve. Not unlike Shirley Horn, one of her primary stylistic models, Krall sings without affect, addressing the lyrics with smoldering clarity and intelligence, phrasing with just the right touch of hornlike elasticity. By this point, she's a phenomenon unto herself.
