On their charismatic self-titled debut album, bluegrass quartet Twisted Pine stay true to their roots while keeping their gaze toward the future. All it takes is one listen to the jazzy harmonies of Kathleen Parks and Rachel Sumner on "Bound to Do It Right" to see the band’s willingness to push the envelope without losing their honeyed, down-home sound (though the rapid-fire mandolin plucking of “Lee Street Tune” proves that they’ve got old-school chops to spare).
