Sky Blue Sky is the sixth studio album by American band Wilco and originally appeared in 2007 on Nonesuch Records. It is the first album with the lineup of Jeff Tweedy, John Stirratt, Glenn Kotche, Mikael Jorgensen, Nels Cline and Pat Sansone, which has remained unchanged since. Compared to the more experimental predecessor Ghost Is Born from 2004, Sky Blue Sky is quieter and more rooted in classic rock and folk traditions. The album was recorded at The Loft, the band's own studio in Chicago.
