From rockabilly barn burners to delicate love songs, Lyle Lovett has become one of America's most beloved singer-songwriters. With a total of 13 albums and songs like "Cowboy Man," "If I Had a Boat" and "I've Been to Memphis," the Texan's pure voice has won him four Grammys -- and along the way, he's also become an in-demand actor. With a whopping 13 Grammys and 26 studio albums, Emmylou Harris is one of the most prolific and popular singer-songwriters in music. Wrecking Ball and Red Dirt Girl found her crossing over into alt rock, but she'll always have a soft spot for country. This dream team of a concert takes place at Los Angeles' most magical venue. With a backdrop of Griffith Park, the Greek Theatre is the perfect setting for this special evening.
