Melody Gardot's 2006 debut, Worrisome Heart, was greeted with warmly enthusiastic reviews that never failed to mention Gardot's musical similarities to Norah Jones and Madeleine Peyroux, or her sadly compelling story of surviving a severe hit-and-run accident at the age of 19.

The tragedy gave critics an irresistible hook, and the musical similarities -- which also include her vocal resemblance to Fiona Apple's smoky tones -- gave new listeners a familiar touchstone, but both merely provided an entry into a fine, accomplished debut.

Released three years later, Gardot's second album, My One and Only Thrill, proves that the first was no fluke; it doesn't build upon the debut so much as it sustains its quality.

Like before, My One and Only Thrill is built primarily on Gardot originals (a fine version of "Over the Rainbow" that closes the album being the only exception) that seamlessly blend sultry, late-night jazz blues, singer/songwriter introspection, and sophisticated pop melodies.

If anything, My One and Only Thrill emphasizes Gardot's chanteuse qualities, feeling like more of a jazz album than its predecessor, thanks both to its languid atmosphere and also Gardot's phrasing, which elegantly elongates her melodies and slips into scat.

These are slight, subtle progressions but what impresses is how thoroughly My One and Only Thrill lives up to the promise of her debut, offering another album that is as enchanting in its sound as it is in its substance.
