What pairs well with any good wine? Live music.

Meghan Trainor is taking ETonline backstage at Live in the Vineyard, where she performed for fans in the gorgeous Napa Valley this past weekend. Also on the bill for the three-day festival were Train, Ingrid Michaelson, Nashville's Jonathan Jackson, Mat Kearney, Echosmith, Matt Nathanson and X Factor alum Bea Miller.

The 20-year-old singer-songwriter may not have been old enough to indulge in Napa's signature beverage, but the experience was still an unforgettable one.

"Performing for that crowd was amazing," Meghan gushes, "'cause they sang back every word that I sang, whether it was my song or other songs."

Back in September, Meghan opened up to ET about her unexpected big break and inspiration for her hit single. She also debuted the ukulele rendition of "Bass," which has quickly become her go-to version for live performances. Watch below!
