Query: Flat and Lackluster

I'm a big fan, of Ms. Clooney, especially of her work with the LA Jazz Choir and the Basie band. This CD is not one of her best, by far. The selections, while adequately performed, were without enthusiasm and variety. The guest artists added some life, but the almost monotone rendering of these tracks did not do justice to her style, skill and potential. They certainly did not live up to the fine sounds and feel of the real music of Brazil.
