‘Paper Airplane’ marks the return of the award-winning Alison Krauss and Union Station. The sound that Krauss and longtime bandmates create is both hauntingly beautiful and familiar, mixing elegance and heartbreak. The bluegrass roots are apparent, but in a way that brings the traditional sound into present day. “Every silver lining always seems to have a cloud that comes my way,” Krauss sings in the opening track. Her voice is the voice of an angel, managing to convey heartache in just a few notes. That, combined with the skilled musicians of Union Station, make this one of the best albums of the year.
