Texas native Sarah Jarosz emerged on the scene as a seventeen-year-old jamming onstage with bluegrass icons David Grisman and Ricky Skaggs, playing her mandolin with a sure touch and real joy. While her instrumental talents are formidable, let's make one thing clear: Sarah is a singer. Her voice is velvety smooth, agile, and powerful occasionally reminiscent of such disparate artists as Natalie Maine's and Patty Griffin. Song Up In Her Head features a mix of 11 original new-old-timey ballads written by Sarah Jarosz, and two well chosen covers, the Decemberists Shankill Butchers and the Tom Waits Come on Up to the House. Collaborators on the album include teenaged peers Samson Grisman and Alex Hargreaves, as well as well-known veterans of the acoustic scene, including Chris Thile, Darrell Scott, Stuart Duncan, Mike Marshall and Jerry Douglas.
