Carmela Pedicini and Tanya Radtke are both established singer/songwriters who have each been leading successful bands in recent years, both developing a substantial following. Together, their harmonies have been described as "magical." As Passerine, they have added David Brain's dobro, for accents that can go from sweet and melodic to a bluesy moan, from the old time mountain sound to more contemporary urban folk and rock. Miles Tweed, with classical training on the double bass, moves from lively and chest-thumping bass lines to slow and melodic accompaniment, pizzicato or played with a bow as fits the music. Occasionally adding mandolin or fiddle into the mix, they have joined their talents in search of an acoustic sound that is simple and compelling, that has both purity and depth, and that adds new musical layers to the tradition of the singer/songwriter.
