If her father Henry's influence can be heard anywhere on Of the Air (Random Chance), it's in Pyeng Threadgill's use of jazz as one element in a wider mosaic, composed also of folk, pop and world music. The singer-songwriter composes with a sense of the totality of her music, presciently aware of the strength of her malleable voice. She doesn't use her backing band (including guitarist Shelley Doty and Zooid cellist Dana Leong) as support, but writes pieces that weave their instruments around her resonant warble. Threadgill's songs are accessible and rich, and her pop sense is fine-tuned enough that she recognized the chamber-jazz potential of The Cure's "Close to Me." Lyrically, too, there is some echo of Dad's work; where Threadgill senior's intricate arrangements of unique instrumentation create a sense of traditional folk music in some fantasy world, Pyeng's sensual imagery is at once earthy and dreamlike.
