Sky Blue Sky has hints of early-seventies southern California folk-rock sweetness in the harmonies.
 
The album is filled with brash guitar solos that take songs like "You Are My Face" and "Shake It Off" in unexpected directions. At first listen these new songs harken back to Wilco's earlier releases, recalling their alt-country roots and eschewing the Jim O'Rourke-inspired noise that made Yankee Hotel Foxtrotsuch a seminal statement.
