One of the most popular music festivals in Napa Valley, the Robert Mondavi Winery Concert Series, returns this summer with one of its strongest lineups ever, featuring Lyle Lovett, Melissa Etheridge and a host of other performers. The 46th annual series, one of the first festivals to adopt the now-routine practice of bringing popular rock and jazz performers to wine country, begins on the Fourth of July with a special fireworks show and performances by The Wallflowers and Andrew McMahon in the Wilderness.
