For a decade, Patty Griffin's prodigious voice and incisive songcraft traveled through an array of musical styles. First, there was busker-Patty playing bygone acoustic folk. Then rocker-Patty, who was married to power chords and massive guitars. And after that, mellow-Patty, who favored barren instrumentation punctuated by her crystal clear vocals. Children contains all these Pattys -- from the stark "You'll Remember" to the funky "Stay on the Ride." Griffin's spiritual sister, Emmylou Harris, joins her on the spare and haunting "Trapeze," a career highlight.
