Fiona Apple’s sister Maude Maggart is a captivating singer in her own right, although stylistically she’s more of a cabaret performer who revels in classics from the Great American Songbook. And while the concept of a modern singer digging into the merry wordplay and bright melodies of such old standards has indeed become increasingly standard, Maggart manages to breathe new life into these well-traveled tunes. Her version of “My Funny Valentine” is icily beautiful instead of predictably mawkish, as she trills with a delicately birdlike quiver that soars airily over a restrained tinkling of piano keys.

She’s just as absorbing when she’s swimming around in a sea of stars on romantic ballads like “Deep Purple” as she is weaving through a thicket of violins and piano on a playful remake of Irving Berlin’s “Pack Up Your Sins.” Maggart infuses her 2007 CD, Dreamland, a collaboration with actor Brent Spiner, with clever production touches, including scraps of evocative dialogue and sound effects, which transform tracks like “I Remember You” from straightforward reinterpretations into something much grander and, yes, dreamier
