Known as “The Sweethearts of Western Harmony,” The Daughters of the Purple Sage sing music of the American West as portrayed on Hollywood’s silver screens of the 1930s and 40s. Their smooth vocals earned them a Group of the Year nomination from the Western Music Association. Accompanying the Daughters is Wylie Gustafson and his band The Wild West. Wylie's unmistakable “Ya-hoo-ooo!” yodel has been heard millions of times as the hallmark of the Yahoo! advertising campaign. This country duo is the last of the World City performances and is sure to end the season with a kick!
