Foster returned to her solo career for 2004's All the Leaves Are Gone, a ghostly and occasionally jarring collection of folk-infused psychedelic rock tunes with her newly formed backing band, the Supposed. It was followed in 2005 by the quiet, rustic, and bluesy Hazel Eyes, I Will Lead You. A Wolf in Sheep's Clothing, an acid-washed rendering of 19th century-style art songs culled from the works of Schubert, Schumann, and Brahms, was released in 2006, followed by This Coming Gladness in 2008 and Graphic as a Star in 2009.
In 2010, Foster released Anda Jaleo, her first collaboration with singer/husband Victor Herrera. It was a new version of Las Canciones Populares, a collection of folk songs first recorded by Federico García Lorca and La Argentinita in 1931. The pair followed it up with Perlas in 2012, an analog, live-in-the-studio collection of forgotten songs and poems drawn from Spanish folk traditions of Castile and the Basque, among other things. Four months later, Foster released Blood Rushing, recorded in Colorado with her husband, the Entrance Band's Paz Lenchantin, Heather Trost (A Hawk and a Hacksaw), and Ben Trimble (Fly Golden Eagle). Back in the U.S. in 2013, she began recording with a small cast of Nashville musicians; the end result was I'm a Dreamer, released in November; it was easily her most conventional offering to date. Drawing on her own catalog, Foster revisited a number of earlier songs on 2016's No More Lamps in the Morning, which she and Herrera tracked live in the studio on a pair of nylon-stringed guitars. ~ James Christopher Monger
