Following the release of "From the Moon to the Sun", Winger studied with Michael Kurek and composed a thirty-minute symphonic piece, "Ghosts", written for strings, piano and harp for a ballet commission. The work had its premiere with the Tucson Symphony Orchestra on November 14–15, 2009. Choreographer Christopher Wheeldon created the ballet "Ghosts", which premiered at the San Francisco Ballet on February 9, 2010, with set design by Laura Jellinek, lighting design by M.L. Geiger and costume design by Mark Zappone.
