Country music singer Willie Nelson is scheduled to appear with bluegrass-country music singer Alison Krauss at the Save Mart Center on Tuesday, Aug. 7.

Krauss’ new album, “Windy City,” is her first effort away from her band, Union Station, in a decade. The album has received critical acclaim and two Grammy nominations.
