This charming hang session with Norah Jones, jazzy singersongwriter Sasha Dobson and alt-rock session vet Catherine Popper began as three friends blowing off steam at a pool hall – think of it as a slacker version of Dolly Parton, Emmylou Harris and Linda Ronstadt's Trio project. Most bar bands don't manage trio harmonies near this gorgeous, but the song selection is uneven. A cover of Wilco's "Jesus, Etc." is a keeper; their take on Neil Young's "Down by the River," not so much. Dobson's "Sex Degrees of Separation" (rhymes with "we'll screw our way to salvation") is the highlight, dubious puns notwithstanding. It's a promising sign.
